“CAS Reg­istry reg­is­ters 70 mil­lionth sub­stance — 07 Dec 2012

Chem­i­cal infor­ma­tion provider Chem­i­cal Abstracts Ser­vice (CAS), a divi­sion of the Amer­i­can Chem­i­cal Soci­ety, has announced a major mile­stone for the CAS Reg­istry, the largest col­lec­tion of pub­licly dis­closed chem­i­cal sub­stance infor­ma­tion. CAS sci­en­tists reg­is­tered the 70 mil­lionth sub­stance from a patent appli­ca­tion sub­mit­ted to the Korean Intel­lec­tual Prop­erty Office (KIPO).

The 70 mil­lionth sub­stance is a poten­tial T-type cal­cium chan­nel blocker dis­cov­ered at the Korea Insti­tute of Sci­ence and Tech­nol­ogy (KIST), a mul­ti­dis­ci­pli­nary research insti­tute in Seoul, South Korea. Assigned CAS Reg­istry Num­ber® 1411769–41-9, the sub­stance is one of sev­eral pyrazolyl-piperazine com­pounds dis­closed in the patent appli­ca­tion pub­lished by KIPO on Novem­ber 14, 2012. This mol­e­cule may be use­ful in the treat­ment of epilepsy, Parkinson’s dis­ease, demen­tia and other conditions.

Sim­i­lar to the 60 mil­lionth sub­stance reg­is­tered in May 2011, the 70 mil­lionth sub­stance again reflects the value of patents as an impor­tant source of chem­i­cal infor­ma­tion. In fact, more than 70 per­cent of new sub­stances from the lit­er­a­ture reg­is­tered in 2012 orig­i­nated from patents. To ensure the com­plete­ness and qual­ity of the CAS pre­mier sub­stance col­lec­tion, CAS sci­en­tists analyse, organ­ise and curate chem­istry in patents from 63 patent author­i­ties around the world.

Chemistry journals information — CASSI

Posted on by

“The CAS Source Index (CASSI) search tool is a web-based resource intended to sup­port researchers and librar­i­ans who need accu­rate bib­li­o­graphic infor­ma­tion. This new tool has been cre­ated as a free-of-charge resource that will enable researchers to con­firm jour­nal titles and jour­nal title abbre­vi­a­tions in an eas­ily acces­si­ble elec­tronic format.

 

This free, web-based tool can serve as a com­pan­ion tool to CASSI on CD cus­tomers to pro­vide easy access for basic jour­nal and abbre­vi­a­tion look-ups, while CASSI on CD pro­vides addi­tional func­tion­al­ity and data such as hold­ings infor­ma­tion, DDS avail­abil­ity, cer­tain record details, and archival abil­ity. To start using the new CASSI search tool, visit http://cassi.cas.org.”

Chemical Abstracts Service and FIZ Karlsruhe strengthen partnership

“Sci­en­tific infor­ma­tion ser­vices provider FIZ Karl­sruhe, Ger­many, and Chem­i­cal Abstracts Ser­vice (CAS), a divi­sion of the Amer­i­can Chem­i­cal Soci­ety, recently signed an agree­ment to fur­ther strengthen a part­ner­ship that began in 1983 with the foun­da­tion of STN Inter­na­tional. STN Inter­na­tional is an online ser­vice for patent and research information.”

“Begin­ning Jan­u­ary 2010, a team of sci­en­tists at FIZ Karl­sruhe will per­form value-added index­ing of selected lit­er­a­ture doc­u­ments, accord­ing to the con­ven­tions used by CAS to make the infor­ma­tion acces­si­ble within the CAS databases.”

“FIZ Karl­sruhe joins a global net­work of sci­en­tists whose exper­tise con­tributes to CAS data­base build­ing. Teams of sci­en­tists in Ohio, India, China, Japan and else­where con­sti­tute the prin­ci­pal con­trib­u­tors to this more than 100 year-old resource.”

US CAS REGISTRY on track to reg­is­ter 50 mil­lionth chem­i­cal sub­stance - 18 Aug 2009

“Chem­i­cal Abstracts Ser­vice (CAS), a divi­sion of the Amer­i­can Chem­i­cal Soci­ety, has announced that it is on track to reg­is­ter the 50 mil­lionth unique chem­i­cal sub­stance on Sep­tem­ber 7. The CAS REGISTRY claims to be the most com­pre­hen­sive and high-quality com­pendium of pub­licly dis­closed chem­i­cal infor­ma­tion. This mile­stone comes only 9 months after CAS reg­is­tered its 40 mil­lionth substance.

REGISTRY is the only inte­grated com­pre­hen­sive source of chem­i­cal infor­ma­tion from a full range of patent and jour­nal lit­er­a­ture that is curated and qual­ity con­trolled by sci­en­tists work­ing around the world. For more than 100 years, CAS sci­en­tists and col­leagues in sev­eral nations have metic­u­lously analysed and indexed pub­licly dis­closed global sci­en­tific infor­ma­tion to build up the unique REGISTRY resource that pro­vides not only chem­i­cal names, the unique CAS Reg­istry Num­ber, and vital lit­er­a­ture ref­er­ences but also ancil­lary infor­ma­tion such as exper­i­men­tal and pre­dicted prop­erty data (boil­ing and melt­ing points, etc.), com­mer­cial avail­abil­ity, prepa­ra­tion details, spec­tra, and reg­u­la­tory infor­ma­tion from inter­na­tional sources.

CAS sci­en­tists fol­low rig­or­ous cri­te­ria that main­tain high qual­ity and reli­a­bil­ity of infor­ma­tion in its REGISTRY. Sci­en­tists iden­tify rep­utable sources and use con­sis­tent analy­sis before reg­is­ter­ing a sub­stance. REGISTRY is avail­able to sci­en­tists through CAS’ prod­uct, SciFinder, and its STN fam­ily of prod­ucts. With these advanced search and analy­sis tech­nolo­gies, CAS helps sci­en­tists find reli­able infor­ma­tion that is vital to their research process.”

 CAS launches free web-based resource for non-chemists - 15 May 2009

 Chem­i­cal Abstracts Ser­vice (CAS), a divi­sion of the Amer­i­can Chem­i­cal Soci­ety, has launched a new, free, web-based resource called Com­mon Chem­istry. This resource is help­ful to non-chemists and oth­ers who might know either a chem­i­cal name or a CAS Reg­istry Num­ber of a com­mon every­day chem­i­cal and want to pair both pieces of information.

Com­mon Chem­istry con­tains nearly 7,800 chem­i­cals of wide­spread and gen­eral inter­est, as well as all 118 ele­ments from the peri­odic table. With the excep­tion of some of the ele­ments, all other sub­stances in this col­lec­tion were deemed of wide­spread inter­est by hav­ing been cited 1,000 or more times in the CAS databases.

While not intended to be a com­pre­hen­sive CAS Reg­istry Num­ber (CAS RN) lookup ser­vice, Com­mon Chem­istry does pro­vide access to infor­ma­tion on chem­i­cals of gen­eral inter­est. The CAS Reg­istry Num­ber is recog­nised through­out the world as the most com­monly used, unique iden­ti­fier of chem­i­cal sub­stances. The full CAS REGISTRYSM data­base con­tains more than 46 mil­lion organic and inor­ganic sub­stances. Research dis­cov­ery and patent tools such as SciFinder and STN allow users to search the entire database.
