84304-76-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84304-76-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,3,0 and 4 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 84304-76:
(7*8)+(6*4)+(5*3)+(4*0)+(3*4)+(2*7)+(1*6)=127
127 % 10 = 7
So 84304-76-7 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.
