124791-09-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124791-09-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,7,9 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 124791-09:
(8*1)+(7*2)+(6*4)+(5*7)+(4*9)+(3*1)+(2*0)+(1*9)=129
129 % 10 = 9
So 124791-09-9 is a valid CAS Registry Number.

A facile and general method for the preparation of α-disulfones (R1SO2SO2R2)
Bartmann
, p. 490 - 496 (2007/10/02)
Dialkyl, diaryl and alkyl aryl disulfones are easily prepared by oxidation of N,N'-disulfonylhydrazines with nitric acid. The method is compatible with a wide variety of substituents (R1,R2) on the sulfur atoms.
