Oxirane, ethynyl-, also known as vinyl oxirane or ethylene oxide, is a colorless, flammable, and highly reactive organic compound with the chemical formula C2H2O. It is a cyclic ether, consisting of a three-membered ring with one oxygen atom and two carbon atoms, and an additional carbon-carbon double bond. Ethynyl oxirane is widely used as a monomer in the production of various polymers, such as polyether polyols, which are key components in the manufacture of polyurethane foams, adhesives, and elastomers. Due to its high reactivity, it is also employed as a chemical intermediate in the synthesis of other organic compounds. However, it is important to note that ethylene oxide is a hazardous substance, classified as a human carcinogen, and requires proper handling and storage to ensure safety.

6924-81-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6924-81-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,2 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.Calculate Digit Verification of CAS Registry Number 6924-81:
(6*6)+(5*9)+(4*2)+(3*4)+(2*8)+(1*1)=118
118 % 10 = 8
So 6924-81-8 is a valid CAS Registry Number.
