  We extract a set of values for the Gross-Llewellyn Smith sum rule at
different values of 4-momentum transfer squared ($Q^{2}$), by combining revised
CCFR neutrino data with data from other neutrino deep-inelastic scattering
experiments for $1 < Q^2 < 15 GeV^2/c^2$. A comparison with the order
$\alpha^{3}_{s}$ theoretical predictions yields a determination of $\alpha_{s}$
at the scale of the Z-boson mass of $0.114 \pm^{.009}_{.012}$. This measurement
provides a new and useful test of perturbative QCD at low $Q^2$, because of the
low uncertainties in the higher order calculations.
