Check Digit Verification of cas no

The CAS Registry Mumber 5745-37-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,4 and 5 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5745-37:
(6*5)+(5*7)+(4*4)+(3*5)+(2*3)+(1*7)=109
109 % 10 = 9
So 5745-37-9 is a valid CAS Registry Number.

Rhodium-catalyzed thiophosphinylation and phosphinylation reactions of disulfides and diselenides

Arisawa, Mieko,Ono, Tetsuya,Yamaguchi, Masahiko

, p. 5669 - 5671 (2005)

Alkyl and aryl dithiophosphinates were synthesized by the reaction of disulfides with biphosphine disulfides in the presence of RhH(PPh 3)4 and 1,2-diphenylphosphinoethane (dppe). The catalyst also promoted synthesis of thiophosphinates and selenothiophosphinates from disulfides and diselenides.
