13397-25-6 Usage
General Description
Chalk is a soft, white, porous, sedimentary carbonate rock composed primarily of the mineral calcite. It is a form of limestone that has undergone metamorphism and recrystallization, resulting in a fine-grained, smooth texture. Chalk is primarily comprised of calcium carbonate, with small amounts of clay and silt. It is commonly used in the production of chalk sticks for writing and drawing, as well as in industrial applications such as the manufacturing of cement and as a filler in paint and plastics. Chalk is also used in agriculture as a soil additive to improve the pH balance and nutrient content of the soil.Check Digit Verification of cas no
The CAS Registry Mumber 13397-25-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,3,9 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.Calculate Digit Verification of CAS Registry Number 13397-25:
(7*1)+(6*3)+(5*3)+(4*9)+(3*7)+(2*2)+(1*5)=106
106 % 10 = 6
So 13397-25-6 is a valid CAS Registry Number.
