94040-09-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 94040-09-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,0,4 and 0 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 94040-09:
(7*9)+(6*4)+(5*0)+(4*4)+(3*0)+(2*0)+(1*9)=112
112 % 10 = 2
So 94040-09-2 is a valid CAS Registry Number.

Reactions of 2,3-dihydro-3-thioxo-thienoisothiazole 1,1-dioxides with diazomethane and diazoethane

Unterhalt,Moghaddam

, p. 317 - 319 (2007/10/02)

2,3-Dihydro-3-thioxo-thieno[2,3-d]isothiazole 1,1-dioxide and 2,3-Dihydro-3-thioxo-thieno[3,2-d]isothiazole 1,1-dioxide are reacted with diazoalkanes in ether/methanol to give 3-alkylthio derivatives and 2-alkyl-3-alkylen products. These can be synthesized directly from the 2-methyl-3-thioxo compounds, for example, by adding diazomethane or diazoethane. The isomers with diazoethane are separated.
