Check Digit Verification of cas no

The CAS Registry Mumber 91552-19-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,5,5 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 91552-19:
(7*9)+(6*1)+(5*5)+(4*5)+(3*2)+(2*1)+(1*9)=131
131 % 10 = 1
So 91552-19-1 is a valid CAS Registry Number.

Room temperature C(sp2)-H oxidative chlorination: Via photoredox catalysis

Zhang, Lei,Hu, Xile

, p. 7009 - 7013 (2017)

Photoredox catalysis has been developed to achieve oxidative C-H chlorination of aromatic compounds using NaCl as the chlorine source and Na2S2O8 as the oxidant. The reactions occur at room temperature and exhibit exclusive selectivity for C(sp2)-H bonds over C(sp3)-H bonds. The method has been used for the chlorination of a diverse set of substrates, including the expedited synthesis of key intermediates to bioactive compounds and a drug.
