Deletion of European chemical Substances Information System

Comment: My first reason for ''weak keep'' is that there is at least one reliable source, so  is not a ground for deletion. My second rationale for ''keep'' is that there are no arguments presented for the deletion. The same short copy-pasted text for each AfD and PROD nominations (already more than hundred, I think) does not convince that the nominator has really and deeply checked the article and available sources, and concerned other possible actions. Deletion should be the last available action if the article really can't be  salvaged, not something for starting the improvement process
Stance: keep
