In the chembox under "Hazards", the recomended source gives the CAS registry number as [1344-81-6], while another source gives [20548-54-3]. If somebody could find the correct calcium sulfide it might help - D Hill 01:10, 31 May 2006 (UTC)

IIRC, isn't calcium sulfide also luminescent - one of the the blue glow-in-the-dark materials - just as zinc sulfide is generally green? The Doctor Is On (talk) 05:41, 3 August 2012 (UTC)
