Check Digit Verification of cas no

The CAS Registry Mumber 445475-41-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,5,4,7 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 445475-41:
(8*4)+(7*4)+(6*5)+(5*4)+(4*7)+(3*5)+(2*4)+(1*1)=162
162 % 10 = 2
So 445475-41-2 is a valid CAS Registry Number.

Stereocontrolled synthesis of a prototype library of enantiopure 2,4-disubstituted 4-aryl-6-piperidinones and piperidines

Hanessian, Stephen,Van Otterlo, Willem A.L,Nilsson, Ingemar,Bauer, Udo

, p. 1995 - 1998 (2002)

Addition of a set of aryl cuprates to N-Boc O-TBDPS 2-hydroxymethyl 3,4-unsaturated 6-piperidinones affords syn-adducts in preference to anti when mixed Grignard-cuprates are used. Aryllithio cuprates give more of the anti-isomer in some cases. A library of 2-hydroxymethyl carbamates (27 compounds) and 2-hydroxymethyl aryl ethers and thioethers (19 compounds) was generated from a selection of 4-aryl-6-piperidinones, and some were further reduced to the corresponding piperidines (9 compounds).
