It really depends, check the backlinks portfolio-if it's spammy, the domain has most likely been penalized and that's why it's deindexed. Do not only depend on metrics.
If your validity search is passed by the domain, go ahead and register it, it can get indexed again as the reason why it has been deindexed is simply because it has expired for a long time.
