133-63-1 Usage
General Description
2,2'-methylenebis[6-tert-butylphenol] is a chemical compound composed of two molecules of 6-tert-butyl-2,2,4-trimethyl-1,2-dihydroquinoline bound together by a methylene bridge. 2,2'-methylenebis[6-tert-butylphenol] is often used as a stabilizer in the production of rubber and other polymers, and it helps to prevent degradation caused by heat, oxygen, and ozone. It is also used as an antioxidant in lubricants and fuels to prevent the formation of harmful by-products. 2,2'-methylenebis[6-tert-butylphenol] is considered to be relatively non-hazardous, with low acute toxicity, and is generally regarded as safe for use in industrial applications when handled and stored properly.
Check Digit Verification of cas no
The CAS Registry Mumber 133-63-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 133-63:
(5*1)+(4*3)+(3*3)+(2*6)+(1*3)=41
41 % 10 = 1
So 133-63-1 is a valid CAS Registry Number.
