Abstract
We evaluate in closed form the parity-violating one-loop six-point function with external gauge bosons in type-I superstring theory. The amplitude is proven finite for arbitrary internal symmetry. The axial-vector anomaly is obtained for general internal symmetry and is shown to vanish in the case of SO(32).
