Chemical Abstracts Service (CAS) Records 50 Millionth Substace in CAS Registry

From the Announcement:

Chemical Abstracts Service (CAS), a division of the American Chemical Society, announced that on September 7 it recorded the 50 millionth substance in CAS REGISTRY, the world's most comprehensive and high-quality compendium of publicly disclosed chemical information. The recently registered substance is a novel arylmethylidene heterocycle with analgesic properties. {Our emphasis] Reaching the 50 million mark so quickly is an indicator of the accelerating pace of scientific knowledge. CAS registered the 40 millionth substance just nine months ago-in contrast, it took 33 years for CAS to register the 10 millionth compound in 1990.

Much more about this milestone in this ResourceShelf post from last week including info about the free CAS "Common Chemistry" database.
