Chalk, a soft, white, porous sedimentary carbonate rock, is primarily composed 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 mainly comprised of calcium carbonate, with trace amounts of clay and silt.

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.
