Well, their subject line was "discourages" and in this case, it is "objecting to encourage". So, basically, they are just stating that they do not like it, which we should note and continue to do what's best for Wikipedia. One might also spend a few hours to talk to them, telling that it should be in their own interest that a) the CAS numbers are mentioned in the articles and b) the numbers should be correct.
In the meantime, I extracted a list for 2200 chemicals from dewp that have their own CAS number mentioned in the template structure (thanks to Lars Aronssons script. I put that list at http://en.wikipedia.org/wiki/Wikipedia_talk:WikiProject_Chemistry/CAS_valida... for reference purposes. Anyone with a (preferrably recent) dump of enwp could so the same for comparison reasons.
