General Description
7-(acetylamino)-4-hydroxy-2-Naphthalenesulfonicacid, also known as AHNS, is a synthetic organic compound commonly used as a fluorescent whitening agent and optical brightener in various industrial applications. It is a derivative of naphthalenesulfonic acid and contains both an acetylamino group and a hydroxy group, making it effective in enhancing the brightness and color of materials such as plastics, textiles, paper, and detergents. AHNS is also used in the pharmaceutical industry as a fluorescent dye for cell imaging and cancer research. However,
Check Digit Verification of cas no
The CAS Registry Mumber 6334-97-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,3 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6334-97:
(6*6)+(5*3)+(4*3)+(3*4)+(2*9)+(1*7)=100
100 % 10 = 0
So 6334-97-0 is a valid CAS Registry Number.
