21368-80-9 Usage
General Description
4-Ethynylphenyl ether, also known as 4-ethynylphenol or 4-ethynylphenyl, is an organic compound with the chemical formula C8H6O. It is a phenyl ether derivative that contains an ethynyl group, which is a triple-bonded carbon at position 4 of the phenyl ring. 4-Ethynylphenyl ether is often used as a building block in organic synthesis and can be utilized in the production of various pharmaceuticals, dyes, and organic compounds due to its unique reactivity and structure. It is a colorless to pale yellow liquid with a pungent odor and is considered to be a potential environmental contaminant. Its precise applications and uses may vary depending on the specific industry and research context in which it is employed.
Check Digit Verification of cas no
The CAS Registry Mumber 21368-80-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,3,6 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21368-80:
(7*2)+(6*1)+(5*3)+(4*6)+(3*8)+(2*8)+(1*0)=99
99 % 10 = 9
So 21368-80-9 is a valid CAS Registry Number.
