552-85-2 Usage
General Description
p-Hydroxynorephedrine, also known as 4-Hydroxynorephedrine, is a chemical compound that belongs to the family of phenethylamines and acts as a sympathomimetic agent. It is a derivative of ephedrine, a stimulant and appetite suppressant often found in over-the-counter cold and allergy medications. p-Hydroxynorephedrine is reported to have similar effects to ephedrine, including increased heart rate, blood pressure, and metabolism, and has been used as a weight loss aid and performance enhancer. However, its use is controversial and has been banned in some countries due to its potential to cause adverse cardiovascular effects and its association with abuse and dependence. In addition to its stimulant properties, p-Hydroxynorephedrine has also been studied for its potential as an anti-inflammatory agent.
Check Digit Verification of cas no
The CAS Registry Mumber 552-85-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,5 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 552-85:
(5*5)+(4*5)+(3*2)+(2*8)+(1*5)=72
72 % 10 = 2
So 552-85-2 is a valid CAS Registry Number.
