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, it is important to note that AHNS can be harmful if ingested or inhaled, and proper safety precautions should be taken when handling this chemical.
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.
