Tris-p-tert.-butylphenylmethylphenylsulfid, also known as 2,4,6-tri-tert-butylphenylmethylphenylsulfid, is a chemical compound with the molecular formula C31H41S. It is a white crystalline solid that is insoluble in water but soluble in organic solvents. Tris-p-tert.-butylphenylmethylphenylsulfid is primarily used as a radical scavenger and a photostabilizer in the polymer industry, particularly in the production of polyolefins, to prevent degradation caused by heat, light, and oxygen exposure. It functions by intercepting free radicals, thus protecting the polymer from chain scission and discoloration, and extending its service life.

Check Digit Verification of cas no

The CAS Registry Mumber 70285-45-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,2,8 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 70285-45:
(7*7)+(6*0)+(5*2)+(4*8)+(3*5)+(2*4)+(1*5)=119
119 % 10 = 9
So 70285-45-9 is a valid CAS Registry Number.
