Used in Laundry Detergents:
Fluorescent Brightener 33 is used as a brightening agent in laundry detergents to make fabrics appear brighter and whiter. It works by absorbing ultraviolet light and re-emitting it as visible light, thus improving the overall appearance of washed clothes.
Used in Whitening Agents:
Fluorescent Brightener 33 is used as a key component in whitening agents to achieve a whiter and cleaner look for various materials. Its ability to absorb ultraviolet light and convert it into visible light contributes to the enhanced brightness and whiteness of the treated surfaces.

Check Digit Verification of cas no

The CAS Registry Mumber 61902-19-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,9,0 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 61902-19:
(7*6)+(6*1)+(5*9)+(4*0)+(3*2)+(2*1)+(1*9)=110
110 % 10 = 0
So 61902-19-0 is a valid CAS Registry Number.
