16451-66-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 16451-66-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,4,5 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 16451-66:
(7*1)+(6*6)+(5*4)+(4*5)+(3*1)+(2*6)+(1*6)=104
104 % 10 = 4
So 16451-66-4 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
