Check Digit Verification of cas no

The CAS Registry Mumber 65837-75-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,8,3 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 65837-75:
(7*6)+(6*5)+(5*8)+(4*3)+(3*7)+(2*7)+(1*5)=164
164 % 10 = 4
So 65837-75-4 is a valid CAS Registry Number.

Photochemistry of Sulfur Compounds Related to the 1,2-Dithiole System. Part 8. Photoisomerization 1',2'-Dithiol-3':4-ylidene-2-cyano-2-butene Nitriles

Pedersen, Carl Th.,Lohse, Christian,Mollier, Yves,Catel, Jean-Marie

, p. 493 - 496 (2007/10/02)

A series of twelve 1',2'-dithiol-3',4-ylidene-2-cyano-2-butene nitriles has been prepared and its photochemistry studied.The stable Z-form is converted into the E-form on irradiation of ethanolic solutions.The photoproducts revert to starting material by a thermal process which obeys first-order kinetics.The influence of substitutents is studied.
