Mistake

 * There are several numbers that are pandigital, including zero, and remain so when multiplied by several factors. For example, $1,098,765,432$ when multiplied by $2$, $4$, $5$ or $7$.

$8$ has been overlooked:


 * $1 \, 098 \, 765 \, 432 \times 8 = 8 \, 790 \, 123 \, 456$

As the article in which this factoid focused on the fact that $123,456,789 \times 8 = 987 \, 654 \, 312$, this omission looks to be a mistake.
