Check Digit Verification of cas no
The CAS Registry Mumber 198976-43-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,9,7 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 198976-43:
(8*1)+(7*9)+(6*8)+(5*9)+(4*7)+(3*6)+(2*4)+(1*3)=221
221 % 10 = 1
So 198976-43-1 is a valid CAS Registry Number.

A new asymmetric synthetic route to substituted piperidines
Reddy, M. Somi,Narender,Rao, K. Rama
, p. 331 - 336 (2007)
An asymmetric synthesis of substituted piperidines has been described. β-Cyclodextrin- or oxazaborolidine-catalyzed asymmetric reduction of α-azido aryl ketones to the corresponding alcohols has been employed as the key step along with ring closing metathesis and selective dihydroxylation.
