Description
(R,E)-methyl 2-(3-(acetylthio)-3-(3-(2-(7-chloroquinolin-2-yl)vinyl)phenyl)propyl)benzoate is a complex organic compound that serves as a reagent in the synthesis of Montelukast Sodium Salt (M568000), a pharmaceutical agent with significant therapeutic applications.
Used in Pharmaceutical Industry:
(R,E)-methyl 2-(3-(acetylthio)-3-(3-(2-(7-chloroquinolin-2-yl)vinyl)phenyl)propyl)benzoate is used as a reagent for the preparation of Montelukast Sodium Salt, which is a selective leukotriene D4-receptor antagonist. This makes it instrumental in the development of antiasthmatic medications, providing a targeted approach to treating asthma and other respiratory conditions by blocking the action of leukotrienes, which are inflammatory mediators.
Check Digit Verification of cas no
The CAS Registry Mumber 855473-48-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,5,4,7 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 855473-48:
(8*8)+(7*5)+(6*5)+(5*4)+(4*7)+(3*3)+(2*4)+(1*8)=202
202 % 10 = 2
So 855473-48-2 is a valid CAS Registry Number.
