Manufacturing Process
A suspension of 40 g 2-amino-3-methylbenzoic acid methyl ester in 125 ml of
benzene was added 125 ml of saturated solution of sodium acetate and then
at 0-5°C was added 37 g chloracetylchloride. The mixture was stirred for 1
hour at room temperature. The mixture was filtered. The organic layer was
with 10% solution of potassium carbonate and dries under calcium chloride.
By distillation of the mixture was obtained 15 g of 2-(2-chloroacetylamino)-3-methylbenzoic acid methyl ester; melting point 86-87.5°C (crystallization from
a mixture acetic acid and ligroin); yield 21.8 g.
A mixture of 16 g of 2-(2-chloroacetylamino)-3-methylbenzoic acid methyl
ester and 10 g diethyl amine in benzene was refluxed for 5 hours. After
cooling the diethyl amine hydrochloride was deleted by filtration. The organic
layer was washed with 2 N hydrochloric acid. To the solution was added
potassium carbonate. The product was extracted with ether and distilled.

Check Digit Verification of cas no
The CAS Registry Mumber 3686-58-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,8 and 6 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3686-58:
(6*3)+(5*6)+(4*8)+(3*6)+(2*5)+(1*8)=116
116 % 10 = 6
So 3686-58-6 is a valid CAS Registry Number.
