84282-69-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84282-69-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,2,8 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 84282-69:
(7*8)+(6*4)+(5*2)+(4*8)+(3*2)+(2*6)+(1*9)=149
149 % 10 = 9
So 84282-69-9 is a valid CAS Registry Number.

AN EFFICIENT METHOD FOR THE CONVERSION OF ARYLHYDRAZINES INTO 2-ARYL-4,4-DIALKYLSEMICARBAZIDES
Pilgram, K. H.
, p. 697 - 706 (2007/10/02)
Arylhydrazines are converted into 2-aryl-4,4-dialkylsemicarbazides by subsequent reaction with chloroformate, phosgene, dialkylamine, and alkaline hydrolysis.
