Tim and Noel thanks a lot for the info and links. Looks very useful. I didn't know about HOSE codes. It seems hard though to use those to generate a atoms label that you can use in a pdb file (max 4 characters ; since I'm working with 3D structures that would be convenient) Regarding the symmetry

Try circular fingerprints. Open Babel has two: MolPrint2D and MNA. See http://baoilleach.webfactional.com/site_media/ob-docs/FileFormats/Utility.html NMRShiftDB uses circular fingerprints (HOSE codes to be exact) for just this purpose. In fact, it might be worth while implementing HOSE codes for O
