Cobalt sulfides occur widely as minerals, comprising major sources of all cobalt compounds. Binary cobalt sulfide minerals include the cattierite (CoS 2) and linnaeite (Co 3 S 4). CoS 2 (see image in table) is isostructural with iron pyrite, featuring disulfide groups, i.e. Co 2+ S 2 2−. Linnaeite, also rare, adopts the spinel motif. [2]

Calcium sulfite, or calcium sulphite, is a chemical compound, the calcium salt of sulfite with the formula CaSO 3 ·x(H 2 O). Two crystalline forms are known, the hemihydrate and the tetrahydrate, respectively CaSO 3 ·½(H 2 O) and CaSO 3 ·4(H 2 O). [2]
The relationship between a CAS Registry Number and an INCI name is not always one-to-one. In some cases, more than one INCI name may have the same CAS number, or more than one CAS number may apply to an INCI name. For example, the CAS number 1245638-61-2 has the CA Index Name of 2-Propenoic acid, reaction products with pentaerythritol.
