Check Digit Verification of cas no

The CAS Registry Mumber 22535-49-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,5,3 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 22535-49:
(7*2)+(6*2)+(5*5)+(4*3)+(3*5)+(2*4)+(1*9)=95
95 % 10 = 5
So 22535-49-5 is a valid CAS Registry Number.

Photopolymerization and photophysical properties of amine linked benzophenone photoinitiator for free radical polymerization

Temel, Gokhan,Enginol, Burak,Aydin, Meral,Balta, Demet Karaca,Arsu, Nergis

, p. 26 - 31 (2011)

Synthesis of amine linked type II photoinitiator (BPDEA) was achieved in high yields and photopolymerization of mono and multiacrylate monomers was performed with this photoinitiator in the absence of a coinitiator. BPDEA is more effective than benzophenone (BP) with the coinitiator (MDEA) system under inert atmosphere in photoinduced free radical polymerization of acrylates.
