Check Digit Verification of cas no

The CAS Registry Mumber 120422-19-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,4,2 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 120422-19:
(8*1)+(7*2)+(6*0)+(5*4)+(4*2)+(3*2)+(2*1)+(1*9)=67
67 % 10 = 7
So 120422-19-7 is a valid CAS Registry Number.

Reactions of Aminopyridine Derivatives with 1-Aryl-3-phenyl-2-propyn-1-ones

Fouli, F. A.,Shaban, M. E.,El-Nagdy, I. E.,Youssef, A. S. A.

, p. 358 - 360 (2007/10/02)

1-Aryl-3-phenyl-2-propyn-1-ones (1a-c) react with 2-amino-(IIa)- and 2-amino-5-chloro-(IIb)-pyridines to give 3-(pyrid-2-ylamino)-(IIIa-c)- and 3-(5-chloropyrid-2-ylamino)-(IIId-f)-1-aryl-3-phenyl-1-propen-1-ones, respectively. 2,3-Diamino-pyridine reacts with 1b and 1c to give 1-aryl-3-phenyl-3-(2-amino-3-iminopyrid-3-yl)-2-propen-1-ones (Va-Vb) and pyridodiazepines (VIb, VIc).However, reaction of Ia with 2,3-diaminopyridine gives only the diazepine (VIa).The structures of the products are based on elemental analyses and spectral data.
