As a chemist I have to disagree:

the number is in fact : 6.02214076×10^23

And it refers to the number of Carbonatoms in isotopically pure C12. Natural Hydrogen has an atomic Mass of 1.008, so the numb er is About 0.8 percent off, since you gave an accuracy of 1 in 10^9 this is significant...

Of course you are correct. My figures are wrong.

But I still think Avogadro's number is a better answer to the question about a number beginning with A.

I was thinking, many different hexadecimal numbers begin with A, but that couldn't be the answer you'd want, even if technically it's correct.

Anesthesia will come in handy if we have to use hexadecimal numbers.

I suppose they are a bit intimidating to the uninitiated...but don't seem all that hard once you get the hang of them.
