Phenyl ethaneperoxoate, also known as benzyl peroxide or dibenzyl peroxide, is an organic compound with the chemical formula C14H14O2. It is a colorless, crystalline solid that is soluble in organic solvents and slightly soluble in water. Phenyl ethaneperoxoate is primarily used as a polymerization initiator, particularly in the production of polystyrene and other polymers. It is also employed as a cross-linking agent in the rubber industry and as a catalyst in various chemical reactions. Due to its reactive nature, phenyl ethaneperoxoate can decompose upon exposure to heat or light, releasing oxygen and forming benzyl radicals, which can lead to the breakdown of the compound and the formation of new chemical bonds.

Check Digit Verification of cas no

The CAS Registry Mumber 4091-65-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,9 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4091-65:
(6*4)+(5*0)+(4*9)+(3*1)+(2*6)+(1*5)=80
80 % 10 = 0
So 4091-65-0 is a valid CAS Registry Number.
