3,3,9,9-Tetraphenyl-2,4,8,10-tetraoxaspiro<5,5>undecan is a complex organic compound characterized by its unique spiro structure and multiple phenyl groups. This molecule features a spiro core, which is a type of cyclic compound where two rings share a common atom. In this case, the spiro core is a 5,5-undecane, which means it has 11 carbon atoms in total, with the spiro atom being one of the five carbons in each ring. The compound is further distinguished by the presence of four oxygen atoms that form oxa bridges within the molecule, contributing to its stability and reactivity. The four phenyl groups attached to the carbon atoms at positions 3, 3, 9, and 9 enhance the compound's aromatic character and influence its physical properties, such as solubility and melting point. This chemical is of interest in organic chemistry for its potential applications in materials science and as a precursor in the synthesis of more complex molecules.

4552-70-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4552-70-9 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 2 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4552-70:
(6*4)+(5*5)+(4*5)+(3*2)+(2*7)+(1*0)=89
89 % 10 = 9
So 4552-70-9 is a valid CAS Registry Number.
