In this article, we examine the concurrent impact of magnetic field, thermal radiation, buoyancy force, viscous dissipation and chemical reaction on Casson fluid flow, over a permeable stretching. The nonlinear model equations are obtained and transformed into a system of ordinary differential equations (ODE). Using shooting technique along with 6 th order Runge-Kutta iteration scheme, the model problem is tackled numerically. The effect of various embedded parameters on the velocity, temperature and concentration distributions are explained graphically while the skin friction coefficient, Nusselt number and Sherwood number are analysed and given in tabular form
