2-Acetoxy-2'-(2,5-diacetoxy-3-tert.-butyl-phenoxy)-5,5'-dimethoxy-4,4'-di-tert.-butyl-biphenyl is a complex organic compound with the molecular formula C32H42O8. It is characterized by a biphenyl core, which consists of two benzene rings connected by a single bond. The compound features multiple acetoxy and methoxy groups, which are ester derivatives of acetic acid and methanol, respectively. The presence of tert-butyl groups provides steric hindrance and stability to the molecule. This chemical is known for its antioxidant properties and is commonly used as a stabilizer in polymers and plastics to prevent degradation caused by heat, light, and oxygen exposure. Its complex structure and functional groups contribute to its effectiveness in protecting materials from oxidative stress, thereby extending their lifespan and maintaining their integrity.

Check Digit Verification of cas no

The CAS Registry Mumber 1774-90-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,7 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1774-90:
(6*1)+(5*7)+(4*7)+(3*4)+(2*9)+(1*0)=99
99 % 10 = 9
So 1774-90-9 is a valid CAS Registry Number.
