938184-95-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 938184-95-3 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 5 respectively.
Calculate Digit Verification of CAS Registry Number 938184-95:
(8*9)+(7*3)+(6*8)+(5*1)+(4*8)+(3*4)+(2*9)+(1*5)=213
213 % 10 = 3
So 938184-95-3 is a valid CAS Registry Number.

Synthetic method of anesthetic analgesic drug

-

, (2019/12/29)

The invention discloses a synthetic method of an anesthetic analgesic drug. According to the synthetic method, 4-piperidinecarboxylic acid is used as a raw material and subjected to alkylation, bromination, methylation, acylation and the like to prepare the anesthetic analgesic drug. The method avoids the usage of highly toxic cyanide, so the safety and controllability of operation are improved; the method avoids an elimination reaction in reaction process, thereby accelerating reaction speed and shortening reaction time; and the method reduces reaction temperature, shortens the reaction time,and is more suitable for industrial production.

NEW PROCESS FOR REMIFENTANIL SYNTHESIS

-

Page/Page column 13-14, (2008/12/06)

A process for synthesizing remifentanil or carfentanil, as well as intermediates for use in the preparation of a synthetic opiate or opioid compound by alkylating a substituted 4-piperidine in the presence of a base to form an intermediate that is further alkylated with an electrophilic alkylating agent and acylated to produce the compound.

PROCESS FOR SYNTHESIZING REMIFENTANIL

-

Page/Page column 25, (2008/06/13)

A process for synthesizing remifentanil or carfentanil, as well as intermediates for use in the preparation of synthetic opiate or opioid compounds. The process comprising reacting a 4-amino 4-carbamyl piperidine with a base in a closed reaction chamber at elevated temperature and pressure to form to intermediate which may be esterified with an alcohol, alkylated, and acylated to produce a synthetic opiate or opioid compound.
