Check Digit Verification of cas no
The CAS Registry Mumber 142918-08-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,9,1 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 142918-08:
(8*1)+(7*4)+(6*2)+(5*9)+(4*1)+(3*8)+(2*0)+(1*8)=129
129 % 10 = 9
So 142918-08-9 is a valid CAS Registry Number.

Successive ring methylation of α-piperidino-oximes by repetitive two-step-reaction
Mohrle,Gehlen
, p. 335 - 340 (2007/10/02)
Dehydrogenation of α-piperidino-acetophenonoximes with Hg(II)-edta, followed by Grignard reaction, succeeds in the stepwise ring methylation of the piperidine moiety, both E- and Z-isomers retaining their configurations. The kind of ring connection of the
