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.
