Chem­i­cal data­base provider Chem­i­cal Abstracts Ser­vice (CAS) has announced that CAS Reg­istry now includes 40 mil­lion organic and inor­ganic sub­stances. The CAS Reg­istry is one the most com­pre­hen­sive col­lec­tions of chem­i­cal sub­stances and the CAS Reg­istry Num­ber is the recog­nised global stan­dard for chem­i­cal sub­stance iden­ti­fi­ca­tion. More than 100 mil­lion CAS Reg­istry Num­bers have been assigned to organic and inor­ganic sub­stances and biosequences.

The 40 mil­lionth sub­stance was iden­ti­fied by CAS sci­en­tists in a jour­nal arti­cle pub­lished in Ange­wandte Chemie Inter­na­tional Edi­tion. The arti­cle describes a novel method for the syn­the­sis of poly­cyclic sub­stances with ‘a cen­tral seven-membered car­bo­cy­cle’, includ­ing the 40 mil­lionth substance.

A divi­sion of the Amer­i­can Chem­i­cal Soci­ety, CAS pro­vides the world’s largest and most cur­rent col­lec­tion of chem­i­cal and related sci­en­tific infor­ma­tion, includ­ing the author­i­ta­tive data­base of chem­i­cal sub­stances, the CAS REGISTRY. CAS com­bines these data­bases with advanced search and analy­sis tech­nolo­gies to deliver com­plete, cross-linked and effec­tive dig­i­tal infor­ma­tion envi­ron­ment for sci­en­tific research and dis­cov­ery, includ­ing such prod­ucts as SciFinder, STN, STN Express and STN AnaV­istTM, among others.
