Check Digit Verification of cas no
The CAS Registry Mumber 91933-54-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,9,3 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 91933-54:
(7*9)+(6*1)+(5*9)+(4*3)+(3*3)+(2*5)+(1*4)=149
149 % 10 = 9
So 91933-54-9 is a valid CAS Registry Number.

Synthesis of 4-Hydroxy-N--2-methyl-2H-1,2-benzothiazine-3-carboxamide 1,1-Dioxide and oxoacetic Acid. Major Metabolites of Isoxicam

4-Hydroxy-N--2-methyl-2H-1,2-benzothiazine-3-carboxamide 1,1-dioxide (2), the major oxidative human metabolite of isoxicam (1), and oxoacetic acid (3), the major rat metabolite of isoxicam (1), were synthesized. 2 was synthesized by condensation of the known benzothiazine ester 8 with the isoxazolamine 9b. 9b was synthesized via a nine-step sequence starting with 5-methyl-3-isoxazolecarboxylic acid (14).NBS bromination of 14 gave 5-(bromomethyl)-3-isoxazolecarboxylic acid, which was coverted to the carbamate ester via a Curtius rearrangement of the acid azide.Displacement of bromine with silver acetate gave the acetoxy compound 21.Hydrolysis of 21 gave the unstable 3-isoxazolamine derivative 9a, which was converted to the OSiMe3 derivative 9b.The compound 3 was synthesized by reaction of ethyl oxalyl chloride with 5-methyl-3-isoxazolamine followed by base hydrolysis.
