Check Digit Verification of cas no

The CAS Registry Mumber 4222-17-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,2 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4222-17:
(6*4)+(5*2)+(4*2)+(3*2)+(2*1)+(1*7)=57
57 % 10 = 7
So 4222-17-7 is a valid CAS Registry Number.

Unexpected formation of new photochromic compounds derived from 3,3-diphenyl-3H-naphtho[2,1-b]pyran-1-one

Sousa, Céu M.,Coelho, Paulo J.,Carvalho, Luis M.,Vermeersch, Gaston,Berthet, Jér?me,Delbaere, Stephanie

experimental part, p. 8317 - 8324 (2010/11/02)

Two new unexpected photochromic compounds were obtained from naphtho[2,1-b]pyran-1-one 1. The reaction of this ketone with the silyl enol ether methyl trimethylsilyl dimethylketene acetal, catalyzed by TiCl 4, afforded the photochromic dihydron
