Uses

A cyclic ether impurity of antiasthmatic Montelukast (M568000).

Check Digit Verification of cas no

The CAS Registry Mumber 168214-67-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,8,2,1 and 4 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 168214-67:
(8*1)+(7*6)+(6*8)+(5*2)+(4*1)+(3*4)+(2*6)+(1*7)=143
143 % 10 = 3
So 168214-67-3 is a valid CAS Registry Number.

Improved process for the preparation of montelukast: Development of an efficient synthesis, identification of critical impurities and degradants

Halama, Ales,Jirman, Josef,Bouskova, Olga,Gibala, Petr,Jarrah, A. Kamal

, p. 425 - 431 (2010)

An improved and scalable process for the production of montelukast (Singulair, drug for asthma) based on a new and advantageous method of carrying out the key substitution reaction has been developed. The present procedure is distinguished from the previous solutions in the use of linear or cyclic polyethers, which ensures higher selectivity of the key step. The improved process for the preparation of montelukast is able to minimize a content of impurities and allows the effective production of montelukast and its scale-up.
