70 million substances (CAS)

“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

"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."

Chemical Abstracts Service Registry to hit 50 million substances soon

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.
