Hello everybody !

Does someone know of an "open" molecule structure search on the net ?
What I am looking for is a service consisting of two parts: first, it
should be possible to enter your own structures and a link to a page on
the net where the molecules are described, the other part of the
service should be a structure search engine. The whole thing should be
completely free and open of course. Has enybody heard of something like
this ?
