144223-33-6 Usage
General Description
1-(2-Furoyl)-1H-benzotriazole 97 is a chemical compound commonly used as a UV absorber and light stabilizer in various industrial and consumer products. It acts as a highly efficient photostabilizer, protecting polymers and coatings from degradation caused by UV radiation. 1-(2-Furoyl)-1H-benzotriazole 97 is particularly effective in prolonging the lifespan and maintaining the appearance of plastics, rubber, and adhesives exposed to outdoor or high-energy UV environments. Additionally, it is used in the formulation of sunscreens and other personal care products to protect the skin from UV-induced damage. This chemical plays a crucial role in enhancing the durability and performance of a wide range of materials and products that are susceptible to photodegradation.
Check Digit Verification of cas no
The CAS Registry Mumber 144223-33-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,2,2 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 144223-33:
(8*1)+(7*4)+(6*4)+(5*2)+(4*2)+(3*3)+(2*3)+(1*3)=96
96 % 10 = 6
So 144223-33-6 is a valid CAS Registry Number.
