82491-01-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82491-01-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,4,9 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 82491-01:
(7*8)+(6*2)+(5*4)+(4*9)+(3*1)+(2*0)+(1*1)=128
128 % 10 = 8
So 82491-01-8 is a valid CAS Registry Number.

N-SULPHONYLFORMAMIDRAZONES; PREPARATION AND STRUCTURE
Jakobsen, P.,Treppendahl, S.
, p. 369 - 372 (2007/10/02)
Potentially tautomeric N-sulphonylformamidrazones and models with fixed amide-hydrazone and hydrazide-imide structure have been prepared.The compounds with tautomeric possibilities have been shown to exist only in the amide-hydrazone form by 13C and 1H NM
