655-35-6 Usage

Originator

Intensain,Hoechst,Switz,1963

Uses

Vasodilator (coronary).

Manufacturing Process

18.7 g of 3β-diethylaminoethyl-4-methyl-7-hydroxy-coumarin chlorhydrate are dissolved in 200 cc methyl ethyl ketone and 18 g anhydrous potassium carbonate are added. The mixture is stirred for 1 hour at 70°C and then 12 g bromoacetic acid ethyl ester are allowed to drop in. The reaction mixture is stirred under reflux for 9 hours and then it is filtered off with suction in the heat. The filtrate is concentrated in the vacuum to dryness and the resultantresidue is dissolved in ether. The etheric solution is washed with diluted caustic soda solution for several times and, subsequently, dried with Glauber's salt. By introduction of hydrochloric acid gas into the etheric solution the reaction product is precipitated in the form of chlorhydrate. Yield: 15 g of 3β- diethylaminoethyl-4-methylcoumarin-7-ethyl oxyacetate chlorhydrate having a melting point of 154° to 156°C (= 63% of the theory).The starting material is produced by reacting resorcinol with 2-(2- diethylaminoethyl)acetic acid ethyl ester.

Therapeutic Function

Coronary vasodilator

Check Digit Verification of cas no

The CAS Registry Mumber 655-35-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,5 and 5 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 655-35:
(5*6)+(4*5)+(3*5)+(2*3)+(1*5)=76
76 % 10 = 6
So 655-35-6 is a valid CAS Registry Number.
