Check Digit Verification of cas no

The CAS Registry Mumber 20735-08-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,7,3 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 20735-08:
(7*2)+(6*0)+(5*7)+(4*3)+(3*5)+(2*0)+(1*8)=84
84 % 10 = 4
So 20735-08-4 is a valid CAS Registry Number.

Photochemical reactions of bianthrone and related substances

Abdou, Wafaa M.,Elkhoshnieh, Yehia O.,Sidky, Mahmoud M.

, p. 3595 - 3602 (2007/10/02)

Photocleavage reactions of a wide range of ethylene compounds were investigated. Photosensitized oxygenation resulted in formation of their corresponding ketones. On the other hand, photoreaction of these substrates with elemental sulfur yielded the corresponding thioketones. Furthermore, photobehaviour of some ethylene episulfides also was studied. It could be concluded that UV-irradiation provides a rapid and effective desactivation pathway for this class of compounds.
