Check Digit Verification of cas no

The CAS Registry Mumber 1219-05-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,1 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1219-05:
(6*1)+(5*2)+(4*1)+(3*9)+(2*0)+(1*5)=52
52 % 10 = 2
So 1219-05-2 is a valid CAS Registry Number.

, p. 389 - 392 (2011)

The condensation of o-phenylenediamines with 1,2-dicarbonyl compounds in the presence of citric acid afforded the corresponding quinoxaline derivatives in higher yields at room temperature in ethanol, and most of the reactions were completed in less than 1 min.
