4,4'-Butylidenebis[1,2-dihydro-1,5-dimethyl-2-phenyl-3H-pyrazol-3-one], also known as 4,4'-Butylidenebis(benzophenone), is a chemical compound with the molecular formula C21H22N2O2. It is a white crystalline solid that is widely used as a UV stabilizer and light stabilizer in the plastics industry, particularly for polyolefins, polyvinyl chloride, and polystyrene. 4,4'-Butylidenebis[1,2-dihydro-1,5-dimethyl-2-phenyl-3H-pyrazol-3-one] works by absorbing harmful UV radiation and converting it into a less harmful form of energy, thus protecting the material from degradation and discoloration. It is also known for its excellent compatibility with various polymers and its ability to provide long-term stability and resistance to yellowing.

1461-17-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1461-17-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,6 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1461-17:
(6*1)+(5*4)+(4*6)+(3*1)+(2*1)+(1*7)=62
62 % 10 = 2
So 1461-17-2 is a valid CAS Registry Number.
