Check Digit Verification of cas no
The CAS Registry Mumber 632335-63-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,2,3,3 and 5 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 632335-63:
(8*6)+(7*3)+(6*2)+(5*3)+(4*3)+(3*5)+(2*6)+(1*3)=138
138 % 10 = 8
So 632335-63-8 is a valid CAS Registry Number.

New stereoselective synthesis of 2-allyl-4-nitroalkylpiperidine-2-thiones and their transformation to annulated piperidinones
So?nicki, Jacek G.
, p. 1673 - 1677 (2003)
Highly stereocontrolled access to trans-3-allyl-4nitro-alkyl-1,6-disubstituted δ-thiolactams was achieved starting from piperidine-2-thione or commercially available 2-mercaptopyridine via Michael-addition of nitroalkanes to 5,6-dihydropyridin-2-thiones, S-allylation and thio-Claisen rearrangement. The corresponding lactams obtained by desulfurisation, were found to be suitable precursors for the construction of trans-fused bicyclic 2-piperidinone derivatives (octahydro[2]pyrindinones) in a regio- and stereoselective radical 5-exo-trig annulation process.
