In Roman Numerals, if you say that \( XLIV\times X=CDXL\), you're correct.

Otherwise, \(\overline{XLIV}\times \overline{X}=\overline{CDXL}\) is a mistake and it's not necessarily correct.

For how many ordered six-tuplets \((C,D,I,L,V,X)\) of single digit positive integers \((x\neq 0)\) is this mistake true?

**Note:** All letters must denote different numbers.
