How can I check component/page is published to which target?

Question

I have a situation where I have to find out those publication targets which are deleted some time back in order to unpublish those components/pages which are published and now they are not being unpublished and further not able to delete. (In this case publication targets are not known) I am using coreservice 2011/2013.

Well, As Peter K mentions in the comments it would be interesting to know how did you delete the Publication Targets.

But to fix your issue you can try:

1. Get the Tcm Ids of the deleted Publication Targets (If somehow you can find those or you have it already)
2. And then use Core Service to un-publish the items.

You can you below example function for it:

public void UnPublishComponent(string[] componentId, string[] targets, bool includeChildren)
        {
            UnPublishInstructionData pub = new UnPublishInstructionData();
            pub.ResolveInstruction = new ResolveInstructionData() { IncludeChildPublications = includeChildren, IncludeComponentLinks = false };

            PublishTransactionData[] pubTranData = tridionClient.UnPublish(componentId, pub, targets, PublishPriority.High, null);
        }
