Oct 11 2014 7:02AM	Normal	Acknowledged	Carbon monoxide is shown as having a molecular formula of CH2O Thank you for your feedback. This is a know but that affects a small number of ChemSpider records - We are shortly going to release a fix for this and recalculate all of this .
Nov 24 2013 2:14PM	Normal	Acknowledged	There seems to be discrepancy between molecular formula and the molecule search for carbon monoxide result: ChemSpider ID: 275 Molecular Formula: CH2O property molecular formula search for CO: (3 results - ids) 10606661 (methane hydrate) 5257010 (Oxoniomethyliumato(6-)) 5257011 (Oxoniomethyl) - no carbon monoxide result. I observed similar behavior with other compounds. Is this by design? Thank you for your comments we are looking into this. Please do email us directly with any other examples that you have found.
