Check Digit Verification of cas no

The CAS Registry Mumber 28622-58-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,6,2 and 2 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 28622-58:
(7*2)+(6*8)+(5*6)+(4*2)+(3*2)+(2*5)+(1*8)=124
124 % 10 = 4
So 28622-58-4 is a valid CAS Registry Number.

A novel synthesis of selenosulfides from diselenides by samarium diiodide

Guo,Zhang

, p. 374 - 375 (2007/10/03)

Diselenides were reduced by samarium diiodide in tetrahydrofuran (THF) to produce samarium selenolate. This selenolate anion reacted smoothly with sodium alkyl thiosulfates and phenylsulfenyl chloride to give selenosulfides in moderate to good yields.
