Check Digit Verification of cas no
The CAS Registry Mumber 1643-73-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1643-73:
(6*1)+(5*6)+(4*4)+(3*3)+(2*7)+(1*3)=78
78 % 10 = 8
So 1643-73-8 is a valid CAS Registry Number.

Strategy for the enantioselective synthesis of trans-2,4-disubstituted piperidines: Application to the CCR3 antagonist IS811
Kauffman, Goss S.,Watson, Paul S.,Nugent, William A.
, p. 8975 - 8977 (2007/10/03)
A strategy for the enantioselective synthesis of trans-2,4-disubstituted piperidines is proposed and applied to the preparation of IS811, a potent CCR3 antagonist. The C2 stereocenter is derived from commercial (R)-epichlorohydrin, while the C4 stereocent
