442882-39-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 442882-39-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,2,8,8 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 442882-39:
(8*4)+(7*4)+(6*2)+(5*8)+(4*8)+(3*2)+(2*3)+(1*9)=165
165 % 10 = 5
So 442882-39-5 is a valid CAS Registry Number.

The transposing of isomer yields in the methanolyses of N-substituted quinolinimides by triethylamine
Van Es, Theodorus,Staskun, Benjamin,Karuso, Peter
scheme or table, p. 53 - 61 (2012/06/04)
The effect of triethylamine in transposing the respective yields of the two isomeric esters ensuing from the methanolysis of N-substituted quinolinimides is described and is rationalized with a mechanism.
