4551-59-1 Usage
Originator
Fenalamide,ZYF Pharm Chemical
Uses
Relaxant (smooth muscle).
Manufacturing Process
To a solution of 25.5 g of phenylethylmalonic acid ethyl ester chloride in 100
ml of anhydrous benzene 5.3 g of anhydrous sodium carbonate are added
followed by 11.6 g of N,N-diethylethylenediamine in small portion. After the
spontaneous heat evolution has subsided the mixture is refluxed for 2 hours
until the evolution of carbon dioxide ceases. After cooling the mixture is allowed to stand for some hours, the precipitated sodium chloride is removed
by filtration. The filtrat is evaporated to dryness in vacuo and the residue
distilled at 182-188°C/3 mm Hg.The phenylethylmalonic acid (diethyl amino) ethylamide ethyl ester (free
base) is converted in hydrochloride by bubbling hydrogen chloride into a
diethyl ether solution of the free base; melting point 71-74°C.
Therapeutic Function
Spasmolytic, Smooth muscle relaxant
Check Digit Verification of cas no
The CAS Registry Mumber 4551-59-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,5 and 1 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4551-59:
(6*4)+(5*5)+(4*5)+(3*1)+(2*5)+(1*9)=91
91 % 10 = 1
So 4551-59-1 is a valid CAS Registry Number.
