Can search engines use InChIs?
Yes! An InChI string can be used as a robust web-based query that has high recall and precision. We have written a paper on this titled “Enhancement of the chemical semantic web through the use of InChI identifiers”, which can be found at http://pubs.rsc.org/ej/OB/2005/b502828k.pdf. The supplemental data from this paper can be found at http://www.rsc.org/suppdata/ob/b5/b502828k/index.html. Please contact us at ned24@cam.ac.uk if you have any queries. We have also provided an InChI/Google Web Service which can be found at http://wwmm-svc.ch.cam.ac.uk/wwmm/html/googleinchiserver.html. This allows you to draw a structure into a 2D editor and then at the click of a button all InChI-fied instances of that molecule on the web will be located and summarised for you!!
