Normal sudoku rules apply (no repeats in a row, column, or box).

"Cells" separated by a Roman numeral must sum to that numeral's value. Cages are treated as a single cell for the purposes of the Roman numeral clues.

The value of a cage is equal to the product of the digits contained within it. The values of some cages are given.

Every prime digit (2, 3, 5, 7) that is orthogonally adjacent to another prime digit has been highlighted in light purple.

For reference:
M = 1000
D = 500
C = 100
L = 50

I made this because I wanted to utilize the Roman numerals higher than X and V. Apologies if the abundance of prime number clues make it too easy; I probably would not have been able to solve this without them.
