Triphenylseleno-thiophosphat, also known as triphenyl(seleno)phosphine sulfide, is a chemical compound with the formula (C6H5)3PSe. It is a derivative of triphenylphosphine, where one of the phosphorus-hydrogen bonds is replaced by a phosphorus-selenium bond. Triphenylseleno-thiophosphat is an organophosphorus compound and a member of the phosphine sulfides family. Triphenylseleno-thiophosphat is a colorless, crystalline solid that is sensitive to air and moisture. It is used in various chemical reactions as a reagent or a ligand in coordination chemistry, particularly in the synthesis of organophosphorus compounds and as a precursor for the preparation of other phosphorus-selenium compounds. Due to its sensitivity, it is typically handled under an inert atmosphere and stored away from light and heat.

Check Digit Verification of cas no

The CAS Registry Mumber 58558-74-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,5,5 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 58558-74:
(7*5)+(6*8)+(5*5)+(4*5)+(3*8)+(2*7)+(1*4)=170
170 % 10 = 0
So 58558-74-0 is a valid CAS Registry Number.
