Just a puzzle

These are the rules of calcdoku.

1. The digits 1 through 7 are used only once in each row and column. (There is no region rule like in Sudoku.)

2. The marked regions give a number and an operation (+,−, ×, or ÷). The operation applies to digits in the region, and when applied to the digits in some order, they result in the given number. In the example above, "9+" could have the digits 2, 3 and 4 because 2 + 3 + 4 = 9 . 2+3+4=9. "2-" could have either 1 and 3 (because 3-1 =2) or 2 and 4 (because 4 -2 =2)

3. The single squares that have a single-digit but no operation are simply filled with that digit.

When the puzzle is solved, what are the digits in column G, from top to bottom? (Enter as a seven-digit number.) Those who want to know more about calcdoku click here
