36932-44-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 36932-44-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,9,3 and 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 36932-44:
(7*3)+(6*6)+(5*9)+(4*3)+(3*2)+(2*4)+(1*4)=132
132 % 10 = 2
So 36932-44-2 is a valid CAS Registry Number.

Maleic acid derivatives in the synthesis of 3-substituted 3,4-dihydroquinoxalin-2(1H)-ones
Rozhkov,Ovchinnikov,Kolobov
, p. 137 - 140 (2014/11/07)
A process for preparing 3-substituted 3,4-dihydroquinoxalin-2(1H)-ones is proposed. It is based on the reaction of o-phenylenediamine with amides, di- and mono-esters of maleic acid as well as (E)-3-(5-phenyl-1,3,4-oxadiazol-2-yl) acrylic acid in the pres
