Do you want to extract Something or /Something/976313416535/? Your description isn't consistent.

I don't know r language, but here is a PCRE regex that works for you (at least at regex101), it matches the second last item in the path (i.e. Something)

^.+/K[^/]+(?=/[^/]+/)

Explanation:

^           # beginning of string

  .+        # 1 or more any character

  /         # a slash

  K        # forget all we have seen until this position

  [^/]+     # 1 or more non slash

  (?=       # start lookahead, zero-length assertion to make sure we have after:

    /       # a slash

    [^/]+   # 1 or more non slash (the string wanted)

    /       # a slash

  )         # end lookahead
