We report the magnetoresistance, Hall effect, de Haas-van Alphen (dHvA)oscillations and the electronic structures of single crystal RhSn, which is atypical material of CoSi family holding a large Chern number. The largeunsaturated magnetoresistance is observed with B//[001]. The Hall resistivitycurve indicates that RhSn is a multi-band system with high mobility. Evidentquantum oscillations have been observed, from which the light effective massesare extracted. Ten fundamental frequencies are extracted after the fast Fouriertransform analysis of the dHvA oscillations with B//[001] configuration. Thetwo low frequencies F$_1$ and F$_2$ do not change obviously and the two highfrequencies F$_9$ and F$_{10}$ evolve into four when B rotates from B//[001] toB//[110], which is consistent with the band structure in the first-principlescalculations with spin-orbit coupling (SOC). The extracted Berry phases of therelative pockets show a good agreement with the Chern number $\pm4$ (with SOC)in the first-principles calculations. Above all, our studies indicate that RhSnis an ideal platform to study the unconventional chiral fermions and thesurface states.
