Uses
Used in Pharmaceutical Industry:
3-(4-cyano-4-phenylamino-1-piperidine)propanoic acid methyl ester is used as an impurity compound for Remifentanil, a potent synthetic mu-opioid agonist. Its presence in Remifentanil is controlled and monitored to ensure the safety and efficacy of the drug.
Check Digit Verification of cas no
The CAS Registry Mumber 938184-94-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,8,1,8 and 4 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 938184-94:
(8*9)+(7*3)+(6*8)+(5*1)+(4*8)+(3*4)+(2*9)+(1*4)=212
212 % 10 = 2
So 938184-94-2 is a valid CAS Registry Number.

Page/Page column 9, (2008/06/13)
A process for preparing remifentanil by conversion of the nitrile group of a cyanopiperidinyl propanoate derivative to an ester group. Advantageously, with this process the number of steps for preparing remifentanil from commercial products is significantly reduced, compared to the processes known in the art.
