1,2-Dioxepane, also known as ethylene oxide or oxacycloheptane, is a cyclic ether with the chemical formula C4H8O2. It is a colorless, flammable, and highly reactive gas at room temperature, with a sweet, ether-like odor. Ethylene oxide is an important industrial chemical, primarily used as a building block for the production of various chemicals, such as ethylene glycol, antifreeze, and polyethylene terephthalate (PET). It is also used as a sterilant for medical equipment and as a fumigant in the food industry. Due to its high reactivity, ethylene oxide can be hazardous and is classified as a hazardous air pollutant, posing risks to human health and the environment.

505-63-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 505-63-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,0 and 5 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 505-63:
(5*5)+(4*0)+(3*5)+(2*6)+(1*3)=55
55 % 10 = 5
So 505-63-5 is a valid CAS Registry Number.
