UB, I am just a housewife, but I do think you have this calculation incorrect. Please correct me if I am not correct in my thinking, okay? Deal?
If you are using vowels as numbers, wouldn’t your caculation be: 3nt2rn2t.
The number 1 is the third vowel; the number 2 is the second vowel; and the number 5 is the fifth vowel.
I am trying to figure your word out. “Antirnitu?”
Are you using a different coding?
LOv2s!
Oops!
Smarty pants that I think I am, that last word would be: L4v2s.
rotflmao!!!

It was just my effort at being young and hip.
I guess I failed, huh?
:-p
