Check Digit Verification of cas no

The CAS Registry Mumber 40515-78-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,5,1 and 5 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 40515-78:
(7*4)+(6*0)+(5*5)+(4*1)+(3*5)+(2*7)+(1*8)=94
94 % 10 = 4
So 40515-78-4 is a valid CAS Registry Number.

Aseries of phenyl azides bearing (E)-2-halovinyl groups were synthesized in high yields by treatment of (E)-3-(4-azidophenyl)- and (E)-3-(2-azidophenyl) acrylic acid with N-halosuccinimide in the presence of LiOAc. (E)-4-(2-bromovinyl) phenyl azide, one o

Synthesis of phenylazides and 1-phenyl-1,2,3-triazoles bearing (E)-2-halovinyl group

Zhang,Su,Kuang,Yang

experimental part, p. 452 - 456 (2011/02/17)

Treatment of (E)-3-(4-azidophenyl)and (E)-3-(2-azidophenyl)acrylic acid with N-halosuccinimides in the presence of LiOAc afforded high yields of phenylazides containing (E)-2-halovinyl group. The latter were transformed to different phenyl-1,2,3-triazoles
