Peroxide, acetyl 3-methylbenzoyl, also known as acetylperoxide or 3-methylbenzoyl peroxide, is an organic compound with the chemical formula C9H8O3. It is a colorless, crystalline solid that is highly sensitive to heat, friction, and impact, making it a potentially hazardous substance. Peroxide, acetyl 3-methylbenzoyl is primarily used as a polymerization initiator, particularly in the production of polystyrene and other polymers, due to its ability to decompose and generate free radicals at relatively low temperatures. It is also used as a catalyst in various chemical reactions. However, due to its instability and potential for explosion, it requires careful handling and storage.
The CAS Registry Mumber 712-90-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,1 and 2 respectively; the second part has 2 digits, 9 and 0 respectively. Calculate Digit Verification of CAS Registry Number 712-90: (5*7)+(4*1)+(3*2)+(2*9)+(1*0)=63 63 % 10 = 3 So 712-90-3 is a valid CAS Registry Number.
