Check Digit Verification of cas no
The CAS Registry Mumber 71703-03-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,7,0 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 71703-03:
(7*7)+(6*1)+(5*7)+(4*0)+(3*3)+(2*0)+(1*3)=102
102 % 10 = 2
So 71703-03-2 is a valid CAS Registry Number.

SYNTHESIS AND SOME REACTIONS OF 4-NITRO DERIVATIVES OF IMIDAZOPYRIDIN-2-ONES
Yutilov, Yu. M.,Svertilova I. A.
, p. 80 - 85 (1986)
Imidazopyridine and its N-methyl derivatives do not undergo nitration, but the 2-oxo derivatives of these compounds are easily nitrated when heated.Some properties of the resulting 4-nitroimidazopyridin-2-ones have been studied.
