Check Digit Verification of cas no
The CAS Registry Mumber 451459-99-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,1,4,5 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 451459-99:
(8*4)+(7*5)+(6*1)+(5*4)+(4*5)+(3*9)+(2*9)+(1*9)=167
167 % 10 = 7
So 451459-99-7 is a valid CAS Registry Number.

Liu, Han-Jun,Hung, Shiang-Fu,Chen, Chuan-Lin,Lin, Mei-Huey
, p. 3907 - 3912 (2013/06/27)
A method for the regioselective synthesis of 3-unsubstituted 1-alkyl-1H-indazoles, starting with 2-halobenzonitriles and N-alkylhydrazines, is described. The two-step reaction pathway proceeds through the intermediacy of 1-alkyl-3-amino-1H-indazoles follo
