5662-80-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5662-80-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,6 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5662-80:
(6*5)+(5*6)+(4*6)+(3*2)+(2*8)+(1*0)=106
106 % 10 = 6
So 5662-80-6 is a valid CAS Registry Number.

A Light/Ketone/Copper System for Carboxylation of Allylic C-H Bonds of Alkenes with CO2

Ishida, Naoki,Masuda, Yusuke,Uemoto, Sho,Murakami, Masahiro

supporting information, p. 6524 - 6527 (2016/05/02)

A photo-induced carboxylation reaction of allylic C-H bonds of simple alkenes with CO2 is prompted by means of a ketone and a copper complex. The unique carboxylation reaction proceeds through a sequence of an endergonic photoreaction of ketones with alkenes forming homoallyl alcohol intermediates and a thermal copper-catalyzed allyl transfer reaction from the homoallyl alcohols to CO2 through C-C bond cleavage. An allylic C-H bond of simple alkenes is carboxylated with CO2 in the presence of a substoichiometric amount of a ketone and a catalytic amount of a copper complex under UV irradiation (see scheme).
