Extract Numbers From String (multiple Cells) And SUM Without Adding Additional Column

i have data stored like:

col1

XXXX1244 50
XXXX1519 60
XXXX1244 50
xxxxx1111 10
xxxxx1519 65

the last 4 caracters are numbers. I need to test these numbers and sum the corresponding values them in a single cell without adding new column(SUMIF like).

so in the above example I need to sum all ending at 1244 or 1519, therefore the sum showed in the single cell equals 225

to extract from a single cell: =VALUE(RIGHT(D8;4))

I tried to use an array formula but it seems to crash if a blank cell is in the array
