Trimeperidine, also known as meperidine, is a synthetic opioid analgesic drug primarily used for the management of moderate to severe pain. It is chemically related to phenylpiperidine and has a similar mechanism of action to morphine, binding to the mu-opioid receptors in the central nervous system to provide pain relief. Trimeperidine is administered through various routes, including oral, intramuscular, and intravenous, and is often used in combination with other medications to enhance its analgesic effects. However, it has a higher risk of side effects, such as respiratory depression, addiction, and seizures, particularly when used in high doses or over an extended period. Due to these risks and the availability of safer alternatives, trimeperidine's use has declined in recent years, and it is now less commonly prescribed in clinical practice.

64-39-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 64-39-1 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 6 and 4 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 64-39:
(4*6)+(3*4)+(2*3)+(1*9)=51
51 % 10 = 1
So 64-39-1 is a valid CAS Registry Number.
