See: /*Feist Publications, Inc., v. Rural Telephone Service Co.*/, 499 U.S. 340 (1991) or follow this link: http://en.wikipedia.org/wiki/Feist_v._Rural The circumstances with CAS numbers is slightly different because to get access to the full set of CAS numbers I suspect you have to sign a licensing agreement on re-use, which makes it a matter of *contract* law and not copyright. Perhaps they should increase the limits beyond 10,000 identifiers but the only people who want the whole monty as it were are potential commercial competitors. The people who publish the periodical "Brain" for example at $10,000 a year. Why should I want the complete set of identifiers to be freely available to help them? Personally I think given the head start that the CAS maintainers have on the literature, etc., that different models for use of the identifiers might suit their purposes just as well. Universal identifiers change over time and my concern is with the least semantic friction and not as much with how we get there. Hope you are having a great day!
