13780-03-5 Usage
Description
Calcium bisulfite, also known as calcium hydrogensulfite (Ca(HS03)2), is a compound that exists only in solution. It has a colorless aqueous solution with a distinct smell of sulfur dioxide. Calcium bisulfite is created by dissolving calcium sulfite in an aqueous solution of sulfur dioxide or by passing sulfur dioxide through a suspension of calcium hydroxide.
Uses
Used in the Brewing Industry:
Calcium bisulfite is used as a germicide, preservative, and disinfectant for washing casks at a dilution of 1:1000. It serves to prevent souring and cloudiness of beer and to inhibit secondary fermentation.
Used in the Textile Industry:
In the textile industry, calcium bisulfite is utilized as a bleaching agent for fabrics, where it acts as an antichlor, enhancing the brightness and quality of the textiles.
Used in the Paper Industry:
Calcium bisulfite is extensively used in the manufacture of sulfite cellulose from wood, which is a crucial component in the paper-making process.
Used in Agriculture:
It is also employed in large amounts to disinfect barns, providing a clean and healthy environment for livestock.
Used in Medicine:
Calcium bisulfite serves as an antiseptic in the medical field, helping to prevent infection and promote healing.

Check Digit Verification of cas no
The CAS Registry Mumber 13780-03-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,7,8 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 13780-03:
(7*1)+(6*3)+(5*7)+(4*8)+(3*0)+(2*0)+(1*3)=95
95 % 10 = 5
So 13780-03-5 is a valid CAS Registry Number.
