(rac)-2,2'-diacetoxy-9,9'-spirobifluorene is a complex organic compound characterized by its unique spirobifluorene structure, which consists of two fluorene units connected at their 9-position, forming a spiro junction. The compound is further modified with two acetoxy groups at the 2,2' positions, which are ester functional groups derived from acetic acid. This molecule is of interest in the field of organic chemistry and materials science, particularly for its potential applications in the development of advanced materials, such as in the creation of organic light-emitting diodes (OLEDs) and other optoelectronic devices, due to its specific electronic and optical properties. The racemic nature of the compound indicates that it consists of equal amounts of both the R and S enantiomers, which are mirror images of each other.

70657-79-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 70657-79-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,6,5 and 7 respectively; the second part has 2 digits, 7 and 9 respectively.Calculate Digit Verification of CAS Registry Number 70657-79:
(7*7)+(6*0)+(5*6)+(4*5)+(3*7)+(2*7)+(1*9)=143
143 % 10 = 3
So 70657-79-3 is a valid CAS Registry Number.
