40288-33-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40288-33-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,2,8 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 40288-33:
(7*4)+(6*0)+(5*2)+(4*8)+(3*8)+(2*3)+(1*3)=103
103 % 10 = 3
So 40288-33-3 is a valid CAS Registry Number.

Synthesis and Dimroth Isomerization of Disubstituted 5-Imino-1,2,4-dithiazolidine-3-thiones (Mustard Oil Sulfides)

Tittelbach, Franz

, p. 107 - 117 (2007/10/02)

Treatment of N-substituted dithiocarbamates with N-substituted S-chloroisothiocarbamoyl chlorides leads to disubstituted 5-imino-1,2,4-dithiazolidine-3-thiones.Educts with different aromatic substituents give the diaryl derivatives 5, as expected by the reaction equation.Educts with one aromatic and one aliphatic substituent give 5-alkylimino-4-aryl derivatives 10, regardless which starting component (3, 4, 7, 8) possesses the aliphatic or aromatic substituent.Educts with different aliphatic substituents (7, 8) leads to mixtures of isomeric derivatives 12, 13.Disubstituted 5-imino-1,2,4-dithiazolidine-3-thiones with 5-alkylimino group are able for Dimroth isomerization to 4-substituted 2-alkyl-1,2,4-thiazolidine-3,5-dithones.
