- What parts of bohr model for electron energy states are still valid?
I know that we use quantum mechanic and wave function to calculate probability of finding electrons but is there anything valid about bohr model that we still use it?
A lot of useful semiclassical physics is done based on Bohr-Sommerfeld quantization. In particular, modern versions of it are indispensable in the spectroscopy of large molecules, where the more accurate ab initio methods become numerically too demanding.Where is the Bohr-Sommerfeld quantization still used?

One more older but interesting survey paper:A lot of useful semiclassical physics is done based on Bohr-Sommerfeld quantization. In particular, modern versions of it are indispensable in the spectroscopy of large molecules, where the more accurate ab initio methods become numerically too demanding.
It is also used for meson spectra in constituent quark models: https://arxiv.org/pdf/hep-ph/0412170
