Calcium polysulfides are inorganic compounds composed of calcium, sulfur, and varying numbers of sulfur- sulfur bonds, resulting in a series of compounds with the general formula CaSx, where x represents the number of sulfur atoms. These compounds are primarily used as vulcanizing agents in the rubber industry, promoting the cross-linking of rubber polymers and enhancing their strength and elasticity. Calcium polysulfides are also employed in the production of dyes, pigments, and as a fungicide in agriculture. They are typically produced by reacting calcium sulfide with sulfur vapor at high temperatures, and their properties, such as solubility and reactivity, can vary depending on the number of sulfur atoms present in the molecule.

Check Digit Verification of cas no

The CAS Registry Mumber 8028-82-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,2 and 8 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 8028-82:
(6*8)+(5*0)+(4*2)+(3*8)+(2*8)+(1*2)=98
98 % 10 = 8
So 8028-82-8 is a valid CAS Registry Number.
