Check Digit Verification of cas no
The CAS Registry Mumber 74685-16-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,8 and 5 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 74685-16:
(7*7)+(6*4)+(5*6)+(4*8)+(3*5)+(2*1)+(1*6)=158
158 % 10 = 8
So 74685-16-8 is a valid CAS Registry Number.

A concise, stereoselective synthesis of picenadol
Martinelli, Michael J.,Peterson, Barry C.
, p. 5401 - 5404 (2007/10/02)
A four-step stereoselective synthesis of picenadol (1) is reported, 1,3-Dimethyl-4-piperidone (3) underwent Horner-Wadsworth-Emmons reaction under conditions that did not yield double-bond isomerization, followed by a directed 1,4-addition with an aryl cuprate. Reduction and deprotection then afforded (1).
