Check Digit Verification of cas no

The CAS Registry Mumber 74259-46-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,5 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 74259-46:
(7*7)+(6*4)+(5*2)+(4*5)+(3*9)+(2*4)+(1*6)=144
144 % 10 = 4
So 74259-46-4 is a valid CAS Registry Number.

THE SOLUTION PHOTOCHEMISTRY OF αβ-UNSATURATED SULPHONES

El Tabei, M. A. A. M.,Kirby, Neil V.,Reid, Stewart T.

, p. 565 - 566 (1980)

1-Phenyl-2-(benzenesulphonyl)-ethylene and 1-phenyl-2-(benzenesulphonyl)-prop-1-ene have been shown to undergo Z,E-photoisomerisation, whereas 2-benzenesulphonylindene readily forms ?2 + ?2> photoadducts with 2,3-dimethylbut-2-ene, cyclopentene, and cyclohexene.
