How to remove the first letter from each alphanumeric string in a column?

I have a list of 107 alphanumeric serial numbers that have an extra "S" as the first character that I want to remove.

For example, if a serial number is:

SFNS28O413AD

It would become:

FNS28O413AD

There was a function in Excel that removed the first character if you selected the whole columm, but I can't find anything similar in Google Sheets.
