General Description
Dimethyl 2-thioxo-1,3-dithiole-4,5-dicarboxylate is a sulphur-containing heterocyclic building block. It has been reported to be formed during the reaction of 1,3-dithiolan-2-thiones with dimethyl acetylenedicarboxylate. It is formed as major product during the reaction of ethylene trithiocarbonate with dimethyl acetylenedicarboxylate.
Check Digit Verification of cas no
The CAS Registry Mumber 7396-41-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,9 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7396-41:
(6*7)+(5*3)+(4*9)+(3*6)+(2*4)+(1*1)=120
120 % 10 = 0
So 7396-41-0 is a valid CAS Registry Number.

A preparative method was developed for the synthesis of 1,3-dithiolane-2-thione and 4-phenyl-1,3-dithiolane-2-thione from dibromoethane and 1-phenyl-1,2-dibromoethane and potassium xanthates.It was shown that their reaction with dimethyl acetylenedicarboxylate without a solvent leads to 4,5-dimethoxycarbonyl-1,3-dithiole-2-thione with yields close to quantitative.
