Uses
Different sources of media describe the Uses of 71-82-9 differently. You can refer to the following data:
1. Anti-narcotic agents
2. Levallorphan tartrate is a narcotic-antagonist analgesic that counteracts the respiratory depression and analgesia caused by Morphine (Sulfate: M652290).
Check Digit Verification of cas no
The CAS Registry Mumber 71-82-9 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 7 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 71-82:
(4*7)+(3*1)+(2*8)+(1*2)=49
49 % 10 = 9
So 71-82-9 is a valid CAS Registry Number.

Method for preparing levallorphan tartrate
-
, (2017/08/29)
The invention provides a method for preparing levallorphan tartrate and belongs to the technical field of drug and chemical synthesis. The method takes methoxyphenylacetic acid and 2-(cyclohexenyl)ethylamine as initial raw materials, and comprises nine reaction steps such as acylation condensation, Bischler-Napieralski ring formation reaction, imine reduction, ether bond hydrolysis, resolution, N-alkylation, Grewe cyclization reaction, and salifying. According to the method, the levallorphan tartrate and each intermediate can be obtained at high yield and high purity, and the method can serve as an industrial method for performing large-scale production.
