Abstract: Tom recently emailed me this question: Do you know how to find out how many of the compounds that appear in the chemical literature are mentioned just once? Intrigued, I first set out to find out how many substances , as Chemical Abstracts refers to the them, there were as of 5 June, 2025 . There is a static estimate here (219 million), but to get the most up to date information, I asked CAS directly.
