Bis(biphenyl-2,2'-diyl)allene is a unique organic compound characterized by its molecular structure, which consists of two biphenyl units connected by an allene bridge. Biphenyl is a derivative of benzene, with two phenyl rings joined together, and the allene bridge introduces a carbon-carbon double bond adjacent to a carbon-carbon triple bond. This specific arrangement endows bis(biphenyl-2,2'-diyl)allene with distinct electronic properties and potential applications in materials science, particularly in the development of conjugated systems and organic electronics. The compound's structure also makes it a subject of interest for studies in organic chemistry, as it represents a rare example of a stable allene derivative with significant conjugation.

Check Digit Verification of cas no

The CAS Registry Mumber 4551-24-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,5 and 1 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4551-24:
(6*4)+(5*5)+(4*5)+(3*1)+(2*2)+(1*4)=80
80 % 10 = 0
So 4551-24-0 is a valid CAS Registry Number.
