well i started off by having each number as 0, which would make the first number 9... so using that i carried on running through a few things realising it didn't work... to be honest it was just pick and choose the numbers here and there, at one points i thought it was 7210000100 but realised that weren't right.. so it was a very quick version of trial and error.
