Check Digit Verification of cas no

The CAS Registry Mumber 119741-56-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,7,4 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 119741-56:
(8*1)+(7*1)+(6*9)+(5*7)+(4*4)+(3*1)+(2*5)+(1*6)=139
139 % 10 = 9
So 119741-56-9 is a valid CAS Registry Number.

Alkylation Studies with 5-Cyano-1H-pyrazole-4-carboxylic Acid, Ethyl Ester

Beck, James R.,Aikins, James,Lynch, Michael P.,Rizzo, John R.,Tao, Eddie V.P.

, p. 3 - 6 (2007/10/02)

5-Cyano-1H-pyrazole-4-carboxylic acid, ethyl ester (1) was regioselectively alkylated at N-1 by tertiary carbocations utilizing sulfuric acid catalysis and relatively mild conditions.In the presence of boron trifluoride, the alkylation occured regioselectively at N-2.Reaction of 1 with alkyl halides under basic conditions resulted in mixture of the two isomers with alkylation at N-2 predominating.
