Check Digit Verification of cas no
The CAS Registry Mumber 172374-11-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,3,7 and 4 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 172374-11:
(8*1)+(7*7)+(6*2)+(5*3)+(4*7)+(3*4)+(2*1)+(1*1)=127
127 % 10 = 7
So 172374-11-7 is a valid CAS Registry Number.

Synthesis of The Diaza Analogue of Ellagic Acid
Kanojia, Ramesh M.,Ohemeng, Kwasi A.,Schwender, Charles F.,Barrett, John F.
, p. 8553 - 8556 (2007/10/02)
The novel diaza analogue 2 of DNA-gyrase inhibitor ellagic acid 1 was synthesized via the Ullmann coupling of methyl 2-bromo-3-nitroveratrate 6 which, in turn, was prepared by a 7-step synthesis from 2-bromopiperonal 10 requiring a contrived, regiospecifi
