1,4-Bis-(9-fluorenyliden)-1,4-diphenyl-but-2-en, also known as F8B, is a conjugated diene with a unique structure consisting of two fluorenyl groups connected by a butadiene bridge and two phenyl groups attached to the terminal carbons. This organic compound is widely used in the synthesis of various materials, particularly in the production of high-performance polymers such as poly(arylene-ethynylene)s and polyfluorenes. Due to its rigid and planar structure, F8B contributes to the enhanced thermal and chemical stability of the resulting polymers, making it a valuable building block in the field of advanced materials and electronics.

4963-83-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4963-83-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,6 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.Calculate Digit Verification of CAS Registry Number 4963-83:
(6*4)+(5*9)+(4*6)+(3*3)+(2*8)+(1*3)=121
121 % 10 = 1
So 4963-83-1 is a valid CAS Registry Number.
