Check Digit Verification of cas no
The CAS Registry Mumber 90736-77-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,7,3 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90736-77:
(7*9)+(6*0)+(5*7)+(4*3)+(3*6)+(2*7)+(1*7)=149
149 % 10 = 9
So 90736-77-9 is a valid CAS Registry Number.

Synthesis of 1,3-benzothiazol-2(3H)-one and some its derivatives
Velikorodov,Kuanchalieva,Melent'eva,Titova
, p. 1375 - 1379 (2011)
Acylation of 2-aminobenzenethiol with methyl chloroformate in pyridine gave dimethyl 2,2′-disulfanediylbis( 2,1-phenylene)dicarbamate instead of expected methyl 2-suylfanylphenylcarbamate. Heating of the product with zinc dust in glacial acetic acid led to the formation of 1,3-benzothiazol-2(3H)-one. Alkylation of the latter with 1,2-dibromoethane and allyl bromide, as well as acylation with chloroacetyl chloride, afforded the corresponding 3-substituted derivatives. 3-[3-(Pyridin-2-yl)-4,5-dihydroisoxazol-5-ylmethyl]-1,3- benzothiazol-2(3H)-one was synthesized with high regioselectivity by 1,3-dipolar cycloaddition of 3-allyl-1,3-benzothiazol-2(3H)-one to pyridine-2-carbonitrile oxide generated from N-hydroxypyridine-2-carboximidoyl chloride hydrochloride by the action of triethylamine.
