50 Millionth Unique Chemical Substance Recorded in CAS REGISTRY^SM

CAS announced that on September 7, 2009, that it recorded the 50 millionth substance in CAS REGISTRY, the worlds most comprehensive and high-quality compendium of publicly disclosed chemical information.  The recently registered substance is a novel arylmethylidene heterocycle with analgesic properties.

Reaching the 50 million mark so quickly is an indicator of the accelerating pace of scientific knowledge. CAS registered the 40 millionth substance just 9 months ago. In contrast, it took 33 years for CAS to register the 10 millionth compound in 1990.

For more information, see the CAS press release.
