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."

40 millionth chemical substance — CAS

US CAS registers 40 millionth substance - 04 Dec 2008

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.
