73839-82-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 73839-82-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,8,3 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 73839-82:
(7*7)+(6*3)+(5*8)+(4*3)+(3*9)+(2*8)+(1*2)=164
164 % 10 = 4
So 73839-82-4 is a valid CAS Registry Number.

Zwitterion-Catalyzed Isomerization of Maleic to Fumaric Acid Diesters

Lam, Ying-Pong,Lam, Zachary,Yeung, Ying-Yeung

, p. 1183 - 1190 (2021/01/09)

Fumaric acid diesters are important building blocks for organic synthesis. A class of zwitterionic organocatalysts based on an amide anion/iminium cation charge pair were found to be effective in catalyzing the isomerization of maleic acid diesters to give fumaric acid diesters. Comparison of the performance of different zwitterionic organocatalysts toward the reaction revealed that nonclassical hydrogen bonding was involved in the stabilization of the Michael adduct intermediate.
