Check Digit Verification of cas no

The CAS Registry Mumber 877124-25-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,7,1,2 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 877124-25:
(8*8)+(7*7)+(6*7)+(5*1)+(4*2)+(3*4)+(2*2)+(1*5)=189
189 % 10 = 9
So 877124-25-9 is a valid CAS Registry Number.

Tailoring flavins for visible light photocatalysis: organocatalytic [2+2] cycloadditions mediated by a flavin derivative and visible light

Mojr, Viktor,Svobodová, Eva,Straková, Karolína,Nevesely, Tomá?,Chudoba, Josef,Dvo?áková, Hana,Cibulka, Radek

, p. 12036 - 12039 (2015/07/28)

A new application of flavin derivatives in visible light photocatalysis was found. 1-Butyl-7,8-dimethoxy-3-methylalloxazine, when irradiated by visible light, was shown to allow an efficient cyclobutane ring formation via an intramolecular [2+2] cycloaddition of both styrene dienes, considered as electron-rich substrates, and electron-poor bis(arylenones), presumably proceeding via an energy transfer mechanism.
