Check Digit Verification of cas no

The CAS Registry Mumber 1229652-79-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,9,6,5 and 2 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1229652-79:
(9*1)+(8*2)+(7*2)+(6*9)+(5*6)+(4*5)+(3*2)+(2*7)+(1*9)=172
172 % 10 = 2
So 1229652-79-2 is a valid CAS Registry Number.

Synthesis of (-)-paroxetine via enantioselective phase-transfer catalytic monoalkylation of malonamide ester

Kim, Mi-Hyun,Park, Yohan,Jeong, Byeong-Seon,Park, Hyeung-Geun,Jew, Sang-Sup

, p. 2826 - 2829 (2010)

(Figure presented) A new enantioselective synthetic method of (-)-paroxetine is reported. (-)-Paroxetine could be obtained in 15 steps (95% ee and 9.1% overall yield) from N,N-bis(p-methoxyphenyl)malonamide tert-butyl ester via the enantioselective phase-transfer catalytic alkylation and the diastereoselective Michael addition as the key steps.
