Benzotriazole series, specifically the compound with the CAS number 95-14-7, is a class of UV absorbers widely used in various industries to protect materials from the harmful effects of ultraviolet (UV) radiation. This chemical compound is known for its ability to absorb UV light, thereby preventing the degradation of materials such as plastics, coatings, and textiles that are exposed to sunlight or artificial light sources. The 95-14-7 compound, in particular, is a derivative of benzotriazole that has been modified to enhance its UV absorption properties. It is commonly used in the formulation of sunscreens, as well as in the stabilization of polymers to extend their service life and maintain their appearance. The use of benzotriazole series compounds like 95-14-7 helps to prevent discoloration, brittleness, and other signs of aging in materials that are subjected to prolonged UV exposure.

4000-40-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4000-40-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,0 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4000-40:
(6*4)+(5*0)+(4*0)+(3*0)+(2*4)+(1*0)=32
32 % 10 = 2
So 4000-40-2 is a valid CAS Registry Number.
