Potassium monosulphide, also known as potassium sulfide, is a chemical compound with the formula KS. It is a white crystalline solid that is soluble in water and has a strong, unpleasant odor. This inorganic compound is primarily used in various industrial applications, such as the production of dyes, pigments, and as a reducing agent in chemical reactions. It is also employed in the tanning industry and as a flotation agent in the mining sector. Due to its reactivity, potassium monosulphide should be handled with care, as it can release toxic hydrogen sulfide gas when exposed to moisture or acids.
The CAS Registry Mumber 1312-78-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,1 and 2 respectively; the second part has 2 digits, 7 and 8 respectively. Calculate Digit Verification of CAS Registry Number 1312-78: (6*1)+(5*3)+(4*1)+(3*2)+(2*7)+(1*8)=53 53 % 10 = 3 So 1312-78-3 is a valid CAS Registry Number.
