326-43-2 Usage
Originator
Analexin, Mallinckrodt Inc., US ,1960
Uses
Analgesic; relaxant
(skeletal muscle).
Manufacturing Process
A mixture containing 188 g (0.20 mol) of 2-arninopyridine, 0.55 g of lithium amide and 75 cc of anhydrous toluene was refluxed for 1.5 hours. Styrene oxide (12.0 g = 0.10 mol) was then added to the reaction mixture with stirring over a period of ten minutes. The reaction mixture was stirred and refluxed for an additional 3.5 hours. A crystalline precipitate was formed during the reaction which was removed by filtration, MP 170°C to 171°C. 1.5 g. The filtrate was concentrated to dryness and a dark residue remained which was crystallized from anhydrous ether; yield 6.0 g. Upon recrystallization of the crude solid from 30 cc of isopropyl alcohol, 2.0 g of a light yellow solid was isolated; MP 170° to 171°C.
Therapeutic Function
Analgesic, Muscle relaxant
Check Digit Verification of cas no
The CAS Registry Mumber 326-43-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,2 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 326-43:
(5*3)+(4*2)+(3*6)+(2*4)+(1*3)=52
52 % 10 = 2
So 326-43-2 is a valid CAS Registry Number.
