Octadecanoic acid, 2-sulfo-, monosodium salt, also known as sodium stearate sulfate or sodium octadecanoate sulfate, is a chemical compound with the molecular formula C18H35NaO5S. It is a derivative of stearic acid, a long-chain fatty acid, with a sulfate group attached to the second carbon atom. Octadecanoic acid, 2-sulfo-, monosodium salt is anionic, meaning it carries a negative charge, and is soluble in water. It is commonly used in various industrial applications, such as in the production of detergents, surfactants, and emulsifiers, due to its ability to lower surface tension and form micelles. Additionally, it has applications in the textile and paper industries as a sizing agent and in the pharmaceutical sector as a component in certain drug formulations.

Check Digit Verification of cas no

The CAS Registry Mumber 7173-72-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,7 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7173-72:
(6*7)+(5*1)+(4*7)+(3*3)+(2*7)+(1*2)=100
100 % 10 = 0
So 7173-72-0 is a valid CAS Registry Number.
