107943-61-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 107943-61-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,9,4 and 3 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 107943-61:
(8*1)+(7*0)+(6*7)+(5*9)+(4*4)+(3*3)+(2*6)+(1*1)=133
133 % 10 = 3
So 107943-61-3 is a valid CAS Registry Number.

Copper-Assisted Synthesis of 2-Hydroxyphenyl-1,2-diones from Phenols and 2-Oxoaldehydes
Battini, Narsaiah,Battula, Satyanarayana,Ahmed, Qazi Naveed
, p. 658 - 662 (2016)
An efficient copper(II)-catalyzed protocol for the ortho-functionalization of phenols was developed. A wide variety of 2-oxoaldehydes and phenols were tolerated, and the corresponding 2-hydroxyphenyl-1,2-diones were afforded in appreciable yields.
