116473-91-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116473-91-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,4,7 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 116473-91:
(8*1)+(7*1)+(6*6)+(5*4)+(4*7)+(3*3)+(2*9)+(1*1)=127
127 % 10 = 7
So 116473-91-7 is a valid CAS Registry Number.

Reaction Behaviour of 2-Ethoxycarbonyl-3-hydroxy-N-phenyl-maleimide
Augustin, M.,Jeschke, P.
, p. 599 - 606 (2007/10/02)
The vinylogous acid 1 gives with amines under various conditions the ammonium salts 2a-f. 2-Ethoxycarbonyl-3-chloro-N-phenyl-maleinimide 5 obtained by the chlorination of 1 leads to N-substituted 2-ethoxycarbonyl-maleimides 6a-d and condensed heterocycles
