Uses

Cholinesterase reactivator.

Check Digit Verification of cas no

The CAS Registry Mumber 154-97-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,5 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 154-97:
(5*1)+(4*5)+(3*4)+(2*9)+(1*7)=62
62 % 10 = 2
So 154-97-2 is a valid CAS Registry Number.

A simple process for the preparation of pralidoxime chloride

Unnisa, Lateef,Sumakanth,Rao, B. Leelamaheswara,Divi, Murali Krishnaprasad,Rao, Mysore Aswathanarayana

, p. 431 - 435 (2014/05/06)

Pralidoxime chloride (2-PAM chloride) is an important drug included in National List of Essential Medicines-2003 for treating pesticide poisoning. However, the current methods for its preparation use hazardous methyl halides such as methyl chloride or methyl iodide. In the present work, reaction of pyridine-2- aldoxime with methyl methanesulfonate in acetonitrile gave 2-PAM mesylate in high yields (90%). Use of methyl tosylate in toluene resulted in 2-PAM tosylate (90% yield). Both 2-PAM mesylate and 2-PAM tosylate on treatment with dry hydrogen chloride in isopropanol, resulted in 2-PAM chloride in high yields (90%) and purity (>99%).
