99549-42-5 Usage
General Description
Fluorescent Brightener 263 is a synthetic organic compound that is commonly used as a fluorescent whitening agent in various industries. It belongs to the class of stilbene derivatives and has a molecular weight of 925.10 g/mol. This chemical is typically used in detergents, paper, and textile industries to achieve a brighter and whiter appearance. It works by absorbing ultraviolet light and re-emitting it as visible light, thus enhancing the brightness and appearance of the material it is applied to. However, it is important to use this chemical with caution as it may cause irritation to the skin, eyes, and respiratory system in some individuals, and should be handled in accordance with safety guidelines.Check Digit Verification of cas no
The CAS Registry Mumber 99549-42-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,5,4 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.Calculate Digit Verification of CAS Registry Number 99549-42:
(7*9)+(6*9)+(5*5)+(4*4)+(3*9)+(2*4)+(1*2)=195
195 % 10 = 5
So 99549-42-5 is a valid CAS Registry Number.
