1,4-Bis-((E)-2-phenyl-but-1-en-3-ynyl)-benzene, also known as diphenylethynylbenzene, is an organic compound characterized by a central benzene ring with two phenylbut-1-en-3-ynyl groups attached at the 1,4 positions. This molecule features a conjugated system of alternating single and triple bonds, which extends from the central benzene ring to the terminal phenyl groups. The presence of this extended conjugation can influence the compound's electronic properties, such as its UV-Vis absorption spectrum, and may also affect its reactivity and stability. The compound is of interest in organic chemistry and materials science, potentially for its use in the synthesis of more complex structures or for studying the effects of conjugation on molecular properties.

5384-74-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5384-74-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,8 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.Calculate Digit Verification of CAS Registry Number 5384-74:
(6*5)+(5*3)+(4*8)+(3*4)+(2*7)+(1*4)=107
107 % 10 = 7
So 5384-74-7 is a valid CAS Registry Number.
