It consists of a central tin (Sn) atom bonded to three phenyl groups (C6H5) and a cyanoacetic acid group (C(CN)(CH3)2). The phenyl groups are aromatic rings that contribute to the compound's stability and reactivity, while the cyanoacetic acid group provides a functional group that can participate in various chemical reactions. (C6H5)3SnC(CN)(CH3)2 is known for its potential applications in organic synthesis and as a precursor in the production of other organotin compounds, which have been historically used as biocides and stabilizers in various industrial applications. However, due to environmental and health concerns, the use of organotin compounds has been restricted or banned in many countries.

Calculate Digit Verification of CAS Registry Number 4278-90:
(6*4)+(5*2)+(4*7)+(3*8)+(2*9)+(1*0)=104
104 % 10 = 4
So 4278-90-4 is a valid CAS Registry Number.
