82191-17-1 Usage
General Description
ETHYL 2-(3-OXO-3,4-DIHYDRO-2H-1,4-BENZOTHIAZIN-2-YL) ACETATE is a compound with the chemical formula C13H13NO3S. It is a derivative of benzothiazine, a heterocyclic compound containing both sulfur and nitrogen atoms in its ring structure. This chemical is commonly used as a building block in the synthesis of pharmaceuticals and agrochemicals. It has potential applications in the development of drugs for treating neurological disorders and cardiovascular diseases.ETHYL 2-(3-OXO-3,4-DIHYDRO-2H-1,4-BENZOTHIAZIN-2-YL) ACETATE may also be used in the production of dyes, pigments, and other organic compounds due to its unique structural properties.
Check Digit Verification of cas no
The CAS Registry Mumber 82191-17-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,1,9 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 82191-17:
(7*8)+(6*2)+(5*1)+(4*9)+(3*1)+(2*1)+(1*7)=121
121 % 10 = 1
So 82191-17-1 is a valid CAS Registry Number.

Sulfuryl Chloride Promoted gem -Dichlorination-Dehydrochlorination in Alkyl Benzothiazinylacetates: Synthesis of the Skeleton of Trichochrome Pigments
Jangir, Ravi,Gadre, Smita R.,Argade, Narshinha P.
, p. 2631 - 2634 (2015/09/01)
Chemo- and stereoselective total synthesis of the basic trichochrome skeleton is described starting from o-aminothiophenol and maleic anhydride in very good overall yield. The process involves the synthesis of the corresponding 1,4-benzothiazin-2-ylacetates followed by their sulfuryl chloride induced dihalogenation-dehydrohalogenation and a second condensation with o-aminothiophenol as key steps.

Reaction of o-aminophenol with various maleic anhydrides gave first 2-hydroxymaleanilic acids (4-(2'-hydroxyphenylamino)-4-oxobut-2-enoic acids) (1), which were then converted into the 3-oxo-1,4-benzoxazines (1d-h) and (3f-l) under mild basic conditions:
