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.
