130240-21-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130240-21-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,2,4 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 130240-21:
(8*1)+(7*3)+(6*0)+(5*2)+(4*4)+(3*0)+(2*2)+(1*1)=60
60 % 10 = 0
So 130240-21-0 is a valid CAS Registry Number.

REACTIONS OF N-ARYLSULFONYLQUINONE IMINES WITH ACYLHYDRAZINES
Avdeenko, A. P.,Evgrafova, N. I.,Tolmachev, A. A.
, p. 1131 - 1134 (2007/10/02)
Possible directions for the reaction of N-arylsulfonylquinone imines with acylhydrazines are discussed.Reduction occurs in quinone imines with high redox potentials and hydrazines with high basicity.Otherwise either addition-elimination occurs at the C=N
