60 million chemicals

There are now 60 million chemicals in the CAS Registry, that’s a number equivalent to 3G users in China, the population of the Roman Empire in 70 BC, the age of the Rocky Mountains in years, the number of casualties in WWII, and the votes cast in American Idol. The last time I mentioned the CAS count was September 2009, when it reached 50 million entries. I remember it reaching the 10 million mark in 1990 (a year or so after I’d started working for the Royal Society of Chemistry, RSC). That seemed like a major achievement given that it had taken CAS 33 years to go from 0 to 10 million.

 

 

The 60-millionth substance in the CAS registry is a putative antiviral agentt and has the CAS # 1298016-92-8. It was discovered by researchers at the Institute of Materia Medica, in China and is a patent pending derivative of 2-amino-1,3,4-thiadiazine.

  1. Someone suggested that CAS needs a Twitter feed to announce each new entry. That’s going to be a very busy account as already, there have been more than 228,591 new entries added since I wrote this blog post…
