64306-67-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 64306-67-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,3,0 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 64306-67:
(7*6)+(6*4)+(5*3)+(4*0)+(3*6)+(2*6)+(1*7)=118
118 % 10 = 8
So 64306-67-8 is a valid CAS Registry Number.

Batori, S.,Messmer, A.
, p. 1041 - 1046 (2007/10/02)
New ν-triazolo- and ν-triazolopyrimidinium salts 12a-e, 13a-c have been synthesized via oxidation (i.e. cyclohydrogenation) of the appropriate pyrimidyl ketone arylhydrazones 3a-e, 6a-c using TBB (2,4,4,6-tetrabromocyclohexa-2,5-dien-1-one)
