Check Digit Verification of cas no

The CAS Registry Mumber 247043-59-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,7,0,4 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 247043-59:
(8*2)+(7*4)+(6*7)+(5*0)+(4*4)+(3*3)+(2*5)+(1*9)=130
130 % 10 = 0
So 247043-59-0 is a valid CAS Registry Number.

Photoredox-Controlled β-Regioselective Radical Hydroboration of Activated Alkenes with NHC-Boranes

Dong, Jie,Gao, Liuzhou,Li, Shuhua,Liu, Xueting,Xie, Jin,Zhao, Yue,Zhu, Chengjian,Zhu, Congjun

, p. 12817 - 12821 (2020)

In this Communication, we report an unprecedented β-regioselective radical inverse hydroboration (compared with ionic hydroboration) of α,β-unsaturated amides with NHC-BH3 enabled by photoredox catalysis. Density functional theory (DFT) calculations show that the unique photoredox cycle is a key factor to control the β-regioselective radical hydroboration, by lowering the energy barrier in comparison with other pathways. This protocol provides a general and convenient route to construct a wide range of structurally diverse β-borylated amides in synthetically useful yields under mild conditions.
