91222-50-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91222-50-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,2,2 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 91222-50:
(7*9)+(6*1)+(5*2)+(4*2)+(3*2)+(2*5)+(1*0)=103
103 % 10 = 3
So 91222-50-3 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.
