Check Digit Verification of cas no

The CAS Registry Mumber 120022-21-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,0,2 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 120022-21:
(8*1)+(7*2)+(6*0)+(5*0)+(4*2)+(3*2)+(2*2)+(1*1)=41
41 % 10 = 1
So 120022-21-1 is a valid CAS Registry Number.

Synthesis and pharmacological evaluation of 4,4-disubstituted piperidines

Colapret,Diamantidis,Spencer,Spaulding,Rudo

, p. 968 - 974 (2007/10/02)

A new class of piperidine derivatives is added to the increasing family of compounds related to fentanyl and carfentanil. Herein, we describe the synthesis and pharmacology of a number of 1-(arylethyl)-4-(acylamino)-4-[(acyloxy)-methyl]piperidines such as 9, 15, and 23. As expected, many of these congeners of fentanyl are extremely potent narcotic agonists. The aim of the study was to identify short-acting analgesic agents (i.e. less than 6 min in the mouse hot-plate assay) for possible use in the surgical theater. Many of the drugs proved to be of intermediate and long duration (i.e. 6-15 min and > 15 min, respectively). In addition to analgesic activity, many of the compounds exhibited anesthetic properties as well. The structure-activity relationship for these entities is presented and discussed.
