We present recent QCD results in {nu}-N scattering at the Fermilab CCFR experiment. We present the latest Next-to-Next-to-Leading order strong coupling constant, {alpha}s , extracted from Gross-Llewellyn-Smith sum rule. The value of {alpha}s from this measurement, at the mass of Z boson, is {alpha}{sup NNLO}{sub s} (M{sup 2}{sub Z} ) = 0:114 {sup +0 : 009}{sub -0.012} Measurements of charged current neutrino and anti-neutrino nucleon interactions in the CCFR detector are used to extract the structure functions, F2, xF{sup {nu}}{sub 3} , xF{sup {anti{nu}}}{sub 3} and R(longitudinal) in the kinematic region 0:01 < x < 0:6 and 1 < Q 2 < 300 GeV{sup 2}. The new measurements of R in the x < 0:1 region provide a constraint on the level of the gluon distribution. The x and Q{sup 2} dependence of R is compared with a QCD based fit to previous data. The CKM matrix element jVcs j is extracted from a combined analysis of xF3 and dimuon data.
