Potassium polymetaphosphate (K?Na?[PO?]?) is a water-soluble inorganic compound, commonly used as a food additive, detergent builder, and in various industrial applications. It is a white, odorless, and tasteless powder that exhibits a glassy consistency. Potassium polymetaphosphate is formed by the polymerization of metaphosphoric acid, resulting in a chain-like structure of phosphate groups. It is known for its ability to sequester metal ions, which makes it effective in preventing scale formation and corrosion in water systems. In food products, it acts as a leavening agent, texturizer, and emulsifier, while in detergents, it enhances cleaning power and prevents soil re-deposition. The compound is also used in the production of ceramics, enamels, and as a flame retardant. Its safety profile is generally considered good, with minimal health risks when used in appropriate concentrations.

Check Digit Verification of cas no

The CAS Registry Mumber 7990-53-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,9,9 and 0 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7990-53:
(6*7)+(5*9)+(4*9)+(3*0)+(2*5)+(1*3)=136
136 % 10 = 6
So 7990-53-6 is a valid CAS Registry Number.
