176966-81-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 176966-81-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,9,6 and 6 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 176966-81:
(8*1)+(7*7)+(6*6)+(5*9)+(4*6)+(3*6)+(2*8)+(1*1)=197
197 % 10 = 7
So 176966-81-7 is a valid CAS Registry Number.

Synthesis of homochiral piperidine derivatives from S-glutamic acid. Stereoselective 1,4-addition of organocuprates to a Δ3-piperidine-2-one. A paroxetine analogue

Herdeis,Kaschinski,Karla,Lotter

, p. 867 - 884 (2007/10/03)

Enantiomerically pure S-5-hydroxy-2-piperidinone 4, readily available from S-glutamic acid, serves as a key intermediate for the synthesis of 3,4-trans substituted piperidine derivatives. The substituents in the 4-position are introduced via 1,4-conjugate
