Well, before that, if this DOF calculator works correctly, the DOF is 5,79m (not 7,5m) for the focusing distance of 6,7m (FF & 50mm focal length, F=5.6). But it is still not equal to 6,58m (as in FF & 75mm & 10m distance). I think because the aperture is the variable here to be taken into conderation (because the of the change of distance from 10m to 6,7m). I don't think simply multiplying with 1.5x factor would show the correct result.

Use "." instead of "," as the decimal point (put 6.67 m).
