Description
ACID BLACK 48 is a black fine powder that exhibits properties such as light fastness, soaping, perspiration fastness, oxygen bleaching, and fastness to seawater. It is soluble in ethanol and slightly soluble in soluble fiber element, but insoluble in benzene, acetone, and chloroform organic solvents. When treated with strong sulfuric acid, it turns gray and forms a gray precipitate upon dilution.
Uses
Used in Textile Industry:

Check Digit Verification of cas no
The CAS Registry Mumber 1328-24-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,2 and 8 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1328-24:
(6*1)+(5*3)+(4*2)+(3*8)+(2*2)+(1*4)=61
61 % 10 = 1
So 1328-24-1 is a valid CAS Registry Number.
