143-81-7 Usage

Originator

Butisol sodium,Wallace Labs,USA

Uses

Sedative-hypnotic.

Manufacturing Process

5-sec-Butyl-5-ethylbarbituric acid was prepared from diethyl ester of malonic acid in 3 steps. At the above malonic ester was reacted with C2H5Br and sodium ethylate producing the diethyl ester of ethylmalonic acid, which after a reaction with sodium ethylate and 2-butylbromide gave the ethyl-(2-butyl)- malonic acid diethyl ester. The last one produced the 5-sec-butyl-5-ethylbarbituric acid after a reaction with urea and sodium ethylate. 23 g sodium (1 mol) was dissolved in 300 ml alcohol. To this solution was added a solution of 5-sec-butyl-5-ethyl-barbituric acid (1 mol) in 800 ml alcohol. To a mixture was added 1000 ml benzene, which precipitated the sodium salt of the barbituric acid (butabarbital sodium). The product was filtered and dried.

Therapeutic Function

Hypnotic

Check Digit Verification of cas no

The CAS Registry Mumber 143-81-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,4 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 143-81:
(5*1)+(4*4)+(3*3)+(2*8)+(1*1)=47
47 % 10 = 7
So 143-81-7 is a valid CAS Registry Number.
