For people like me who haven't paid attention, and were taken aback by that: "i. A User or Organization may include, without a license and without paying a fee, up to 10,000 CAS Registry Numbers or CASRNs in a catalog, web site, or other product for which there is no charge. *The following attribution should be referenced or appear with the use of each CASRN: CAS Registry Number is a Registered Trademark of the American Chemical Society*" [1] So up to 10,000 is ok, but will include 10,000 attributions.
