633-47-6 Usage
Originator
Cropropamide,Geigy (Novartis)
Uses
Cropropamide, is the main component of the drug Prethcamide, which is a respiratory stimulant.
Manufacturing Process
2-Chlorbutiric acid dimethyl amide are dissolved in absolute benzene and
heated to 110°C with propylamine in the autoclave. After cooling the
propylamine hydrochloride is filtered off, then the benzene solution is treated
with water and freed from any dissolved propylamine hydrochloride by means
of potassium lye. After distillation of the benzene the 2-propylaminobutyric
acid dimethyl amide is rectified in vacuum.2-Propylaminobutyric acid dimethyl amide is dissolved in benzene and while
cooling, crotonic acid chloride is added and mixed. Then, reaction mixture is
filtered and freed from benzene to give 2-(N-propyl-crotonylamido)butyric acid
dimethyl amide, melting point 128°-130°C.
Therapeutic Function
Respiratory stimulant
Check Digit Verification of cas no
The CAS Registry Mumber 633-47-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,3 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 633-47:
(5*6)+(4*3)+(3*3)+(2*4)+(1*7)=66
66 % 10 = 6
So 633-47-6 is a valid CAS Registry Number.
