No, my "good old" cactus service doesn't do a lookup in this case, it is
read from the string, which is of of course in opposition to what I just
said :-). We did quite a bit regarding normalization, first, the CACTVS
toolkit behind the service is quite good in this regard and I added a few
things for the web service, too.
