To test the corrected scaling relation $\alpha +z=4\mathrm{}-3\delta$ of the conserved Kardar-Parisi-Zhang (CKPZ) equation suggested by Janssen [Phys. Rev. Lett. 78, 1082 (1997)], a stochastic growth model that follows the CKPZ equation with the conserved noise is restudied. We have found a consistent nonzero correction term $\delta ,$ which is somewhat larger than that estimated from the two-loop renormalization group calculation.
