This is the first puzzle I have created. I hope you like the idea I came up with. Any comments will be appreciated

Normal sudoku rules apply.

All lines are product renbans. A product renban contains a set of consecutive digits in any order. Additionally, reading from left to right or from top to bottom a product renban can be divided in three non-overlapping segments A, B and C such that the numerical value of A is smaller than B and A x B = C.

For example: 391867254 is a valid product renban line as it contains the digits 1-9, 39 is smaller than 186 and 39 x 186 = 7254.
