Isobutenedisulfonic acid, also known as 2,2'-dimercapto-N-(2-hydroxyethyl)dibutylamine or 2,2'-iminobis(N-(2-hydroxyethyl)butanamide), is an organic compound with the chemical formula C10H22N2O4S2. It is a colorless to pale yellow liquid that is soluble in water and has a molecular weight of 322.42 g/mol. This chemical is primarily used as a corrosion inhibitor in various industrial applications, such as oil and gas pipelines, water treatment systems, and cooling towers, due to its ability to form protective films on metal surfaces and prevent corrosion. Additionally, isobutenedisulfonic acid is also employed as a chelating agent in detergents and cleaning products, as it can bind to metal ions and help remove them from surfaces.
The CAS Registry Mumber 1561-93-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,6 and 1 respectively; the second part has 2 digits, 9 and 3 respectively. Calculate Digit Verification of CAS Registry Number 1561-93: (6*1)+(5*5)+(4*6)+(3*1)+(2*9)+(1*3)=79 79 % 10 = 9 So 1561-93-9 is a valid CAS Registry Number.
