Manufacturing Process
60 g (1.5 mol) of powdered sodium amide are put in suspension in 800 ml of
toluene. The mixture is heated to 60°C and 166 g of homomyrtenol (1 mol)
are added little by little. The reaction is continued for several hours until the
homomyrtenol is entirely converted into sodium derivative. It is allowed to
stand and the excess amide is filtered. The reaction is followed by titration on
a sample of the decanted liquid after having removed the ammonia.Added to the solution of the sodium derivative of the terpenic alcohol (1 mol)
is a toluenic solution of 138 g (1.02 mol) diethylaminochloroethane in toluene.
This mixture is refluxed in a nitrogen atmosphere for 12 hours. A precipitate
of sodium chloride is formed which is dissolved in water. Two modes of
extraction of the base myrtecaine are possible:A) The toluenic solution is extracted with two times 200 ml of concentrated
hydrochloric acid diluted to 20%. ln this way there is obtained an aqueous
solution of the hydrochloride, when the required amino base is salted out by
addition of potassium carbonate. The amino ether-oxide is finally rectified
under a vacuum. The fraction boiling between 135° and 140°C under 2 to 3
mm is collected; nD20 = 1.477.B) The toluenic solution is dried on potassium carbonate and then rectified.
There is collected the toluene, then between 120° and 130°C under 2 mm the
homomyrtenol which has not reacted, and then between 130° and 145°C a
fraction which is again fractionated. The pure product is collected at 135°-
140°C/2-3mm Hg.

Check Digit Verification of cas no
The CAS Registry Mumber 7712-50-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,1 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7712-50:
(6*7)+(5*7)+(4*1)+(3*2)+(2*5)+(1*0)=97
97 % 10 = 7
So 7712-50-7 is a valid CAS Registry Number.
