129075-89-4 Usage
General Description
4-(1H-1,2,3-Benzotriazol-1-ylmethyl)phenylamine, also known as UV-326, is a chemical compound commonly used as a UV stabilizer in plastics, coatings, and rubber products. It functions by absorbing and dissipating harmful UV radiation, thereby preventing degradation and discoloration of the material. 4-(1H-1,2,3-BENZOTRIAZOL-1-YLMETHYL)PHENYLAMINE is also used in the production of adhesives, sealants, and other industrial applications to improve the durability and longevity of the products. However, there are concerns about the potential environmental and health risks associated with the use of this chemical, leading to regulations and restrictions in some regions. Overall, 4-(1H-1,2,3-Benzotriazol-1-ylmethyl)phenylamine plays a crucial role in protecting various materials from UV damage but its usage needs to be carefully managed due to its potential risks.
Check Digit Verification of cas no
The CAS Registry Mumber 129075-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,0,7 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 129075-89:
(8*1)+(7*2)+(6*9)+(5*0)+(4*7)+(3*5)+(2*8)+(1*9)=144
144 % 10 = 4
So 129075-89-4 is a valid CAS Registry Number.
