2,2,4,5,5-Pentamethyl-3-imidazoline-1-oxyl, also known as PMI or 2,2,4,5,5-pentamethyl-3-imidazoline-1-oxide, is a chemical compound with the molecular formula C9H19N2O. It is a derivative of imidazoline, a heterocyclic compound containing two nitrogen atoms in a five-membered ring. PMI is a colorless, oily liquid with a strong, amine-like odor. It is widely used as a corrosion inhibitor, particularly in the oil and gas industry, to prevent the formation of rust and other types of corrosion in pipelines and storage tanks. Additionally, PMI is employed as a stabilizer in various chemical formulations, such as fuel and lubricant additives, to enhance their performance and longevity. Due to its reactive nature, PMI can form complexes with metal ions, which contributes to its effectiveness as a corrosion inhibitor and stabilizer.

Check Digit Verification of cas no

The CAS Registry Mumber 39753-74-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,7,5 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 39753-74:
(7*3)+(6*9)+(5*7)+(4*5)+(3*3)+(2*7)+(1*4)=157
157 % 10 = 7
So 39753-74-7 is a valid CAS Registry Number.
