Check Digit Verification of cas no
The CAS Registry Mumber 201667-18-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,6,6 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 201667-18:
(8*2)+(7*0)+(6*1)+(5*6)+(4*6)+(3*7)+(2*1)+(1*8)=107
107 % 10 = 7
So 201667-18-7 is a valid CAS Registry Number.

A diastereoselective synthesis of 2,4-disubstituted piperidines: scaffolds for drug discovery.
Watson,Jiang,Scott
, p. 3679 - 3681 (2007/10/03)
A method for the diastereoselective synthesis of 2,4-disubstituted piperidines has been developed which enables the complete control of reaction selectivity merely by changing the order of the reaction sequence. These targets provide convenient platforms
