Clear specific view’s cache programmatically, specific to contextual filter

I am using the following to clear view specific cache on node_presave which is working fine.

  cache_clear_all($view_name.':'.$display_name, 'cache_views_data', TRUE);

Currently, it is deleting all the views generated for all Contextual Filters(taxonomy term id). I want to be able to delete only the view for one taxonomy term id.

For example, if the node a with tid:46 is added,

What is happening: All the following view’s caches are cleared(deleted from cache_views_data table).

articles/45 articles/46 articles/47

What I want to happen: only delete the view’s cache for articles/46.

So, to achieve this I started digging into the tables(mainly cache_views_data) to figure out the pattern of the CID.

There is a UUID like string added to each CID.

enter image description here

What I have known so far is: his String seems to be the same for a particular view. For example, for the view articles/46, it is the same each time. I have tried clearing the cache several times and re-generate it again and again.

I believe that if I can know the correct string for each view, I can clear the caches specifically. So my question is: Is what I am trying to achieve doable? Does the string change based on some unknown factor? If not, is it consistent and dependable? If yes, then how can I know how and where is this generated?

My guess is the views module is using ctools module for this but I don’t know how exactly.
