Octadecyl-H-phosphinic acid, also known as 1-octadecylphosphinic acid or stearic acid phosphinic, is a chemical compound with the molecular formula C18H39PO2. It is a derivative of phosphinic acid, where the hydrogen atom is replaced by an octadecyl group, which consists of a long hydrocarbon chain with 18 carbon atoms. This amphiphilic molecule has both hydrophilic (phosphinic acid) and hydrophobic (octadecyl) properties, making it useful in various applications such as lubricants, surfactants, and corrosion inhibitors. Its unique structure allows it to form stable complexes with metal ions, which can be beneficial in industrial processes and environmental remediation.

Check Digit Verification of cas no

The CAS Registry Mumber 2753-55-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,5 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2753-55:
(6*2)+(5*7)+(4*5)+(3*3)+(2*5)+(1*5)=91
91 % 10 = 1
So 2753-55-1 is a valid CAS Registry Number.
