51811-43-9 Usage
General Description
Fluorescent brightening agent 91 is a chemical used in laundry detergents and other cleaning products to enhance the brightness and whiteness of fabrics by absorbing ultraviolet light and emitting blue light. Its chemical structure consists of a substituted diphenyl-stilbene derivative, which allows it to absorb and emit fluorescent light, therefore making the colors of fabric appear brighter and cleaner. This agent is effective in whitening and brightening fabrics in a variety of temperatures and pH levels, making it a versatile and widely-used additive in the textile industry. Additionally, it is stable in both acidic and alkaline conditions, and is resistant to heat and oxygen, ensuring its effectiveness over a wide range of environmental conditions.Check Digit Verification of cas no
The CAS Registry Mumber 51811-43-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,8,1 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.Calculate Digit Verification of CAS Registry Number 51811-43:
(7*5)+(6*1)+(5*8)+(4*1)+(3*1)+(2*4)+(1*3)=99
99 % 10 = 9
So 51811-43-9 is a valid CAS Registry Number.
