655240-71-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 655240-71-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,5,2,4 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 655240-71:
(8*6)+(7*5)+(6*5)+(5*2)+(4*4)+(3*0)+(2*7)+(1*1)=154
154 % 10 = 4
So 655240-71-4 is a valid CAS Registry Number.

Functionalization of benzo[b][1,6]naphthyridine derivatives
Ivanov,Tugusheva,Alekseeva,Granik
, p. 1182 - 1189 (2007/10/03)
Two routes to consecutive functionalization of 3-chloro-4-cyanobenzo[b][1, 6]naphthyridine (1a) at positions 3 and 10 were developed. Oxidation of compound 1a with m-chloro-perbenzoic acid in acetone leads to 3-chloro-4-cyano-10-oxobenzo[b][1,6]naphthyrid
