A recently published paper  considered the total graph of commutative ring R. In this paper, we compute Wiener, hyper-Wiener, reverse Wiener, Randić, Zagreb, ABC and GA indices of zero-divisor graph.
Connections between radicals of alternative and right alternative rings are investigated, with emphasis on those which are
nondegenerate in the sense that semi-simple rings have no absolute zero-divisors. In particular it is shown that nondegenerate
radicals of right alternative rings have the Anderson-Divinsky-Sulinski property.
