Nonamethylene-diphosphonic acid tetrachloride, also known as 1,9-nonamethylenediphosphonic acid tetrachloride, is a chemical compound with the molecular formula C9H22O6P2Cl4. It is a white crystalline solid that is soluble in water and is commonly used as a scale inhibitor in various industrial applications, such as water treatment and cooling systems. The compound is formed by the reaction of nonamethylenediamine with phosphorus trichloride, resulting in a molecule with two phosphonic acid groups separated by a nonamethylene chain. Its ability to chelate metal ions makes it effective in preventing the formation of scale deposits, which can cause operational issues and equipment damage in industrial settings.

Check Digit Verification of cas no

The CAS Registry Mumber 5943-28-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,4 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5943-28:
(6*5)+(5*9)+(4*4)+(3*3)+(2*2)+(1*8)=112
112 % 10 = 2
So 5943-28-2 is a valid CAS Registry Number.
