Check Digit Verification of cas no

The CAS Registry Mumber 179179-81-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,9,1,7 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 179179-81:
(8*1)+(7*7)+(6*9)+(5*1)+(4*7)+(3*9)+(2*8)+(1*1)=188
188 % 10 = 8
So 179179-81-8 is a valid CAS Registry Number.

Synthesis of Enantiopure trans-3,4-Disubstituted Piperidines. An Enantiodivergent Synthesis of (+)- And (-)-Paroxetine

Amat, Mercedes,Bosch, Joan,Hidalgo, Jose,Canto, Margalida,Perez, Maria,Llor, Nuria,Molins, Elies,Miravitlles, Carles,Orozco, Modesto,Luque, Javier

, p. 3074 - 3084 (2007/10/03)

Reaction of (R)-phenylglycinol with methyl 5-oxopentanoate gave either bicyclic lactam cis-1 (the kinetic product) or its isomer trans-1 (under equilibrating conditions) as the major products, which were converted to the corresponding (cis or trans) unsaturated lactams 4 and 5. On treatment with lithium alkyl (or aryl) cyanocuprates, these chiral building blocks undergo conjugate addition to give enantiopure trans-3,4-substituted 2-piperidone derivatives in high yield and stereoselectivity. The synthetic potential of this transformation is illustrated by the synthesis of (+)-femoxetine and the two enantiomers of the known antidepressant paroxetine.
