823214-65-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 823214-65-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,2,3,2,1 and 4 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 823214-65:
(8*8)+(7*2)+(6*3)+(5*2)+(4*1)+(3*4)+(2*6)+(1*5)=139
139 % 10 = 9
So 823214-65-9 is a valid CAS Registry Number.

Iron-catalyzed oxidative C-C and C-O coupling of halophenols to α-substituted β-keto esters
Regev, Almog,Shalit, Hadas,Pappo, Doron
, p. 1716 - 1725 (2015)
The iron-catalyzed oxidative cross-coupling of halophenols to α-substituted β-keto esters takes place through one of two modes: oxidative C-C coupling or oxidative C-O coupling. A mechanistic investigation revealed that the chemoselectivity of these react
