General Description
Fluorescent brightener 121, also known as 4,4'-bis(2-sulfostyryl)biphenyl disodium salt, is a chemical compound commonly used in laundry detergents and other household products to enhance the appearance of fabrics by making them appear whiter and brighter. It works by absorbing ultraviolet light and emitting visible blue light, which enhances the whiteness and brightness of fabrics. Fluorescent brightener 121 is also used in paper, plastics, and cosmetics industries to achieve similar brightening effects.

The CAS Registry Mumber 12224-11-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,2 and 4 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 12224-11:
(7*1)+(6*2)+(5*2)+(4*2)+(3*4)+(2*1)+(1*1)=52
52 % 10 = 2
So 12224-11-2 is a valid CAS Registry Number.
