7488-55-3 Usage
Uses
Used in Cement Industry:
Stannous sulfate is used as a retarder in grinding portal cement and blended hydraulic cement for improving the quality of cement, mortar, and concrete.
Used in Analytical Chemistry:
It is used as a reducing agent during the determination of mercury, cobalt, and nickel through atomic absorption spectrophotometry.
Used in Battery Industry:
Stannous sulfate is used as an electrolyte additive in batteries, which helps in restraining larger particles of irreversible sulfation in charge-discharge cycles of battery testing.
Used in Metal Finishing:
Stannous sulfate is used in acid tin plating baths, liquor finishing, and drawing of steel wire. It provides a high current efficiency and delivers a bright finish by flow melting through the use of certain additives.
Used in Chemical Synthesis:
It is used in the preparation of stannous salts and serves as a precursor for tin metal.

Check Digit Verification of cas no
The CAS Registry Mumber 7488-55-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,8 and 8 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7488-55:
(6*7)+(5*4)+(4*8)+(3*8)+(2*5)+(1*5)=133
133 % 10 = 3
So 7488-55-3 is a valid CAS Registry Number.
