Monster Cages #

Difficulty: 2
Tags: Sudoku, Chaos Construction, Monster Cages
This puzzle is a chaos construction. Cages indicate the product of each region sum contained in a cage. For instance, if a 4-cell cage contained 1,2 in one region and 3,4 in another region, its total would be (1+2)x(3+4)=80. Cages may be contained in one region, in which case, the total is just the sum of the cells. Digits may not repeat in a cage.
