Check Digit Verification of cas no

The CAS Registry Mumber 863479-23-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,3,4,7 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 863479-23:
(8*8)+(7*6)+(6*3)+(5*4)+(4*7)+(3*9)+(2*2)+(1*3)=206
206 % 10 = 6
So 863479-23-6 is a valid CAS Registry Number.

One-step highly selective borylation/Suzuki cross-coupling of two distinct aryl bromides in pure water

Xu, Shan Dong,Sun, Fang Zhou,Deng, Wei Hang,Hao, Han,Duan, Xin Hong

, p. 16464 - 16468 (2018)

A Na2PdCl4-catalysed B2(OH)4-mediated direct cross-coupling of two distinct aryl bromides in pure water is described. This one-step borylation/Suzuki method exhibits an outstanding cross-coupling selectivity and no tendency to produce homocoupling products, therefore leading to biaryls and heterobiaryls in moderate to good yields. Moreover, the reaction has high regio-selectivity and can be scaled-up. Using such a simple, economical and practical protocol, the unsymmetrical diarylation of 3,5-dibromopryidine is achieved.
