Killer Sudoku

Rules

Fill the grid so that every column, every row and every 3x3 box contains the digits 1 to 9. The regions bordered with a dotted line are called "cages". The sum of all numbers in a cage has to be equal to the small number in its bottom left corner. No number may appear twice in a cage.
