123647-46-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123647-46-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,6,4 and 7 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 123647-46:
(8*1)+(7*2)+(6*3)+(5*6)+(4*4)+(3*7)+(2*4)+(1*6)=121
121 % 10 = 1
So 123647-46-1 is a valid CAS Registry Number.

Ethyl esters of α-(3-chloro-1,4-naphthoquinon-3-yl)crotonic or cinnamic acids were obtained by the reaction of 2,3-dichloro-1,4-naphthoquinone with ethyl esters of N-substituted β-aminocrotonic or β-aminocinnamic acids.These esters were converted by alkal
