91091-52-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91091-52-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,0,9 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 91091-52:
(7*9)+(6*1)+(5*0)+(4*9)+(3*1)+(2*5)+(1*2)=120
120 % 10 = 0
So 91091-52-0 is a valid CAS Registry Number.

Willgerodt reaction in the series of imidazopyridine derivatives
Yutilov,Shcherbina
, p. 564 - 568 (2007/10/03)
2-Methylimidazopyridines readily undergo Willgerodt-Kindler reaction with formation of imidazopyridine-2-carbothioanilides. Intramolecular Willgerodt-Kindler reaction was effected by fusion of 1-(3-acetylamino-4-pyridyl)-2-methyl-1H-imidazo[4,5-c]pyridine
