Check Digit Verification of cas no
The CAS Registry Mumber 64096-91-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,0,9 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 64096-91:
(7*6)+(6*4)+(5*0)+(4*9)+(3*6)+(2*9)+(1*1)=139
139 % 10 = 9
So 64096-91-9 is a valid CAS Registry Number.

The 4H-Pyrazolobenzimidazole ring system was prepared by an intramolecular Ullmann arylation of 4-substituted 1-(o-aminophenyl)pyrazole while other derivatives were obtained by functional group modifications.Some electrophilic substitutions (nitration, bromination) and alkylations were also carried out. - Keywords: Alkylation; Bromination; Nitration; Ullmann arylation
