Check Digit Verification of cas no

The CAS Registry Mumber 211568-52-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,1,5,6 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 211568-52:
(8*2)+(7*1)+(6*1)+(5*5)+(4*6)+(3*8)+(2*5)+(1*2)=114
114 % 10 = 4
So 211568-52-4 is a valid CAS Registry Number.

Organic photoredox catalysis for the oxidation of silicates: Applications in radical synthesis and dual catalysis

Lévêque, Christophe,Chenneberg, Ludwig,Corcé, Vincent,Ollivier, Cyril,Fensterbank, Louis

, p. 9877 - 9880 (2016)

Metal free photooxidation of alkyl bis(catecholato)silicates with the organic dye 1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyano-benzene (4CzIPN) allows the smooth formation of alkyl radicals. The latter can be efficiently engaged either with radical acceptors to provide homolytic addition products or in photoredox/nickel dual catalysis reactions to obtain cross-coupling products.
