2,3-Benzo-1,1-diphenyl-1-sila-2-cyclobutene is a complex organic compound with the molecular formula C22H20Si. It is a derivative of cyclobutene, featuring a benzene ring fused to the cyclobutene structure, and a silicon atom replacing one of the carbon atoms in the cyclobutene ring. The compound is characterized by two phenyl groups attached to the silicon atom, which contributes to its unique electronic and steric properties. This molecule is of interest in the field of organosilicon chemistry, where it may be studied for its potential applications in materials science and as a precursor in the synthesis of more complex silicon-containing compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 733-87-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,3 and 3 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 733-87:
(5*7)+(4*3)+(3*3)+(2*8)+(1*7)=79
79 % 10 = 9
So 733-87-9 is a valid CAS Registry Number.
