The CAS Registry Mumber 75427-20-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,4,2 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 75427-20:
(7*7)+(6*5)+(5*4)+(4*2)+(3*7)+(2*2)+(1*0)=132
132 % 10 = 2

The Nitration of Imidazopyridines

Glover, Edward E.,Peck, Leonard, W.

, p. 959 - 962 (2007/10/02)

Imidazopyridines in acetic acid solution are readily nitrated by nitric acid-sulphuric acid, although in some instances treatment of the base hydrogensulphate with nitric acid-acetic acid is preferred.Nitration occurs most readily in the 1-position, but 3-nitration occurs if the 1-position is already substituted.
