Octamethylen-diphosphonsaeure-tetrachlorid, also known as octamethylene diphosphonic acid tetrachloride or ODPA-Cl4, is a chemical compound with the formula C8H16Cl4O6P2. It is a white crystalline solid that is soluble in water and various organic solvents. ODPA-Cl4 is primarily used as a chelating agent in industrial applications, such as water treatment, metal cleaning, and oil recovery. It forms stable complexes with metal ions, which helps in preventing scale formation, corrosion, and fouling in various systems. The compound is also used as a flame retardant and as a precursor in the synthesis of other phosphorus-containing compounds. Due to its potential environmental and health risks, proper handling and disposal procedures should be followed when working with ODPA-Cl4.

Check Digit Verification of cas no

The CAS Registry Mumber 5943-67-9 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, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5943-67:
(6*5)+(5*9)+(4*4)+(3*3)+(2*6)+(1*7)=119
119 % 10 = 9
So 5943-67-9 is a valid CAS Registry Number.
