This puzzle was inspired in part by a puzzle by Kowadis, which can be seen here.

Normal sudoku rules apply.

The red lines are product lines - in each box that the red line enters, the product of the digits along the line is the same.

In each box, row, and column, one digit for the purposes of the lines has a value of 10. These digits form a set of the digits from 1 to 9.

The cell with the grey circle contains an odd digit.

In the final grid, replace all cells with a value of 10 with a 0 for the answer check.
