Then you may be interested in using one or both of the new services CHECKCIF and PRINTCIF provided by Acta Crystallographica, Section C. Both are automatic program systems, which will accept a CIF by e-mail and mail the results back to you. The relevant addresses are checkcif@iucr.ac.uk and printcif@iucr.ac.uk. Send only the CIF - make sure there is no accompanying message or signature line.
If you experience any problems in using these utilities, please contact Brian McMahon (bm@iucr.ac.uk) or Mike Hoyland (mh@iucr.ac.uk)
