Check Digit Verification of cas no
The CAS Registry Mumber 926913-64-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,6,9,1 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 926913-64:
(8*9)+(7*2)+(6*6)+(5*9)+(4*1)+(3*3)+(2*6)+(1*4)=196
196 % 10 = 6
So 926913-64-6 is a valid CAS Registry Number.

Acylation of tert-butyl 3-(methylamino)but-2-enoate with fluorinated acetic acid anhydrides occurred at the enamine carbon atom. The reaction of the resulting tert-butyl 3-(methylamino)-2-(RFCO)but-2-enoates with alkyl hydrazines resulted in mixtures of isomeric pyrazoles that were easily separated by column chromatography. The target fluorinated pyrazole-4-carboxylic acids were obtained on a multigram scale.
