It's All about the Number

The Puzzler

RAY: This was a puzzler that I'm stealing from the late Martin Gardner. I'm going to give you a number and you're going to tell me what's unique about the following number: 8,549,176,320. Now if you want a hint, I'll point out that there are 10 digits in that number. The question is, what's unique about this number?
