Check Digit Verification of cas no

The CAS Registry Mumber 131738-75-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,7,3 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 131738-75:
(8*1)+(7*3)+(6*1)+(5*7)+(4*3)+(3*8)+(2*7)+(1*5)=125
125 % 10 = 5
So 131738-75-5 is a valid CAS Registry Number.

A concise, stereoselective synthesis of picenadol

Martinelli, Michael J.,Peterson, Barry C.

, p. 5401 - 5404 (1990)

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).
