511-13-7 Usage
Originator
Abehol,Pliva
Uses
A centrally-acting cough suppressant. It has local anesthetic and antihistamine properties, and may have anticholinergic effects at high doses.
Manufacturing Process
To a suspension of 330.0 g of sodamide (moistened with toluene) in 1500 ml
of absolute ether, a solution of 1080.0 g of o-chlorobenzophenone and 350.0
g of acetonitrile in 3500 ml of absolute ether was gradually added dropwise,
with stirring, such that the reaction temperature adjusted itself to 28°-30°C.
The reaction mixture was stirred for 12 to 15 h at room temperature and was
then added carefully to some ice water. The resulting solution was extracted 3
times with ether. The ether solution was washed with water, dried over
Na2SO4, filtered, and finally concentrated. When 1 L of petroleum ether was
added, 1240.0 g (96% of theoretical) of β-phenyl-β-o-chlorophenylhydroacrylonitrile (melting point 90°-92°C) precipitated.
500.0 g of the β-phenyl-β-o-chlorophenyl-hydroacrylonitrile were dissolved in
3 L of methanol and hydrogenated in the presence of 50.0 g of Raney cobalt
at a temperature of 60°-70°C and a pressure of 80-85 ATM. Two moles of
hydrogen were absorbed, and after separation of the methanolic solution from
the catalyst, 450.0 g of 1-o-chlorophenyl-1-phenyl-3-aminopropanol-1 of
melting point 117°C were obtained.
Catalytic methylation of 1-o-chlorophenyl-1-phenyl-3-aminopropanol-1
(hydrogenation in the presence of 2.2 mol of formaldehyde in aqueous
methanol with Raney nickel catalyst) yielded 450.0 g of l-o-chlorophenyl-1-
phenyl-3 dimethylaminopropanol-1 of melting point 120°C.
In practice it is usually used as hydrochloride.

Check Digit Verification of cas no
The CAS Registry Mumber 511-13-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,1 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 511-13:
(5*5)+(4*1)+(3*1)+(2*1)+(1*3)=37
37 % 10 = 7
So 511-13-7 is a valid CAS Registry Number.
