Whether they're non-profit or not, CAS acts precisely as jealous
of its set of numbers as any other commercial database company. The impression I get is that this *is* a significant nuisance for chemists and other scientists. Other entities (I can probably find the details) have attempted to establish their own, freer sets of unique identifiers for chemical compounds, precisely in hopes of avoiding the cumbersome restrictions placed on the use of CAS numbers. But CAS has sued -- and I think successfully -- to discourage this, claiming either that they own the idea of a single master database of unique identifiers for chemical compounds, or that having a competing set of identifiers would sow confusion.
The claim on the idea would fall under "patents", would it not?
