Perchlorate d'acetyle, also known as peracetic acid, is a powerful oxidizing agent with the chemical formula CH3COOOH. It is a colorless liquid with a pungent, vinegar-like odor and is commonly used as a disinfectant, sterilant, and漂白剂 in various industries, including food processing, medical, and wastewater treatment. Peracetic acid is formed by the reaction of acetic acid and hydrogen peroxide in the presence of a catalyst, such as sulfuric acid or perchloric acid. It is effective against a wide range of microorganisms, including bacteria, viruses, fungi, and spores, making it a valuable chemical in maintaining hygiene and controlling infections. However, due to its corrosive and reactive nature, it requires careful handling and storage to prevent accidents and environmental contamination.
The CAS Registry Mumber 2889-74-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,8 and 9 respectively; the second part has 2 digits, 7 and 4 respectively. Calculate Digit Verification of CAS Registry Number 2889-74: (6*2)+(5*8)+(4*8)+(3*9)+(2*7)+(1*4)=129 129 % 10 = 9 So 2889-74-9 is a valid CAS Registry Number.
