Cephalosporin structures 

Hi Antony. I see you've been checking the stereochemistry on the cephalosporin structures, and assigning proper IUPAC names for them. The thing is, I personally checked each of them and the structures actually do appear to match the stereochemistry, at least using the ACD name generator—am I missing something? Thank you again for your massive curation efforts, and please know that I, for one, am wholeheartedly committed to making sure each and every one of my structures is accurate )  (t·c)
