4221-68-5 Usage
General Description
1,1-Bis(3-cyclohexyl-4-hydroxyphenyl)cyclohexane, also known as UV-326, is a chemical compound commonly used as a light stabilizer in various industries, including the production of polymers, paints, and coatings. It is a white to light yellow solid that is insoluble in water but soluble in organic solvents. UV-326 works by absorbing and dissipating the harmful UV radiation that can degrade and discolor materials, helping to extend the lifespan and durability of the products it is added to. Due to its effectiveness in protecting against UV damage, UV-326 is widely used in the manufacturing of plastics, synthetic fibers, and other materials that are vulnerable to sun exposure. However, like many chemical compounds, UV-326 has raised concerns about its potential environmental and health impacts, and its use is regulated in some regions.
Check Digit Verification of cas no
The CAS Registry Mumber 4221-68-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,2 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4221-68:
(6*4)+(5*2)+(4*2)+(3*1)+(2*6)+(1*8)=65
65 % 10 = 5
So 4221-68-5 is a valid CAS Registry Number.
