Check Digit Verification of cas no

The CAS Registry Mumber 87719-08-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,7,1 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 87719-08:
(7*8)+(6*7)+(5*7)+(4*1)+(3*9)+(2*0)+(1*8)=172
172 % 10 = 2
So 87719-08-2 is a valid CAS Registry Number.

, p. 2314 - 2317 (1996)

The reaction of cyanogen bromide (1) with primary amines (2a-p), including arylmethylamines (21-p), gave the corresponding cyanamides (3a- p). Trimerization of 3a-p gave 1,3,5-trisubstituted 2,4,6-triiminohexahydro- 1,3,5-triazines (isomelamines) (4a-p), which were treated with hydrochloric acid to give the corresponding 1,3,5-trisubstituted 2,4,6-trioxohexahydro- 1,3,5-triazines (isocyanurates) (5a-c, f) and 1,3,5-trisubstituted 2-imino- 4,6-dioxohexahydro-1,3,5- triazines (5b'-e'). Biological evaluation of 4a- p, 5a-c, f, and 5b'-e' was carried out, and some of these compounds showed bronchodilator and positive inotropic activities.
