7727-67-5 Usage
Uses
Used in Detergent Manufacturing:
Sodium Tetraphosphate is used as a key ingredient in the production of detergents for its sequestration properties. It helps to bind and remove calcium and magnesium ions in water, preventing the formation of scale and allowing for more effective cleaning.
Used in Photography Industry:
In the photography industry, Sodium Tetraphosphate is used as a developer additive for several reasons. It helps to (1) prevent sludge formation during the mixing, storage, or use of the developer, (2) prevent the formation of scum on the film when in the developer, and (3) greatly reduce the rate at which incrustations accumulate on the tank walls, sprockets, and mechanical parts. This contributes to a smoother and more efficient photographic development process.
Used in Water Treatment:
Sodium Tetraphosphate can also be utilized in water treatment applications as a dispersing agent. Its ability to prevent the formation of unwanted substances makes it a valuable component in maintaining the clarity and quality of water in various systems.

Check Digit Verification of cas no
The CAS Registry Mumber 7727-67-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,2 and 7 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7727-67:
(6*7)+(5*7)+(4*2)+(3*7)+(2*6)+(1*7)=125
125 % 10 = 5
So 7727-67-5 is a valid CAS Registry Number.
