872544-55-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 872544-55-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,2,5,4 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 872544-55:
(8*8)+(7*7)+(6*2)+(5*5)+(4*4)+(3*4)+(2*5)+(1*5)=193
193 % 10 = 3
So 872544-55-3 is a valid CAS Registry Number.

A new route to 3,4-disubstituted piperidines: Formal synthesis of (-)-paroxetine and (+)-femoxetine
Yamada, Shinji,Jahan, Ishrat
, p. 8673 - 8676 (2007/10/03)
A new route to 3,4-disubstituted piperidines was developed using chiral 1,4-dihydropyridines as key intermediates, the synthetic utility of which was demonstrated by formal synthesis of (-)-paroxetine and (+)-femoxetine.
