AS REPORTEDno primary record reached; this is what the reporting says

Is it true that the moment of inertia for a single point particle of mass m about a fixed axis at a distance r is calculated as I = mr^2?

Yes. The claim is supported by standard physics reference materials, which define the moment of inertia for point particles as the product of mass and the squared distance to the axis.
