Let D be a division ring with the center F = Z(D). Suppose
that N is a normal subgroup of D∗ which is radical over F, that is, for any
element x ∈ N, there exists a positive integer nx, such that xnx ∈ F. In [5],
Herstein conjectured that N is contained in F. In this paper, we show that
the conjecture is true if there exists a positive integer d such that nx ≤ d for
any x ∈ N.
