Get-aduser filters

Question

My organization has a lot of users, including limited-use accounts and service accounts. Sometimes I just want to perform a query on "real" users which have a specific format:
1) all "real" users start with the letter "s"
2) they all have a 5 digit number after the "s"
3) they all end with an "n" or a "d"
How would I do a get-aduser to return just the "real" users in my organization? Do I need some sort of regex, or can I use get-aduser -filter 'samaccountname -like xxxxx' ?
Thank you

I don't think you'd need a loop, at the worst, a where-object piped after:
$users = get-aduser -filter * | Where-Object {$_.samaccountname -match "[Ss]{1}[0-9]{5}[NnDd]{1}"}

Don't discount the provider filter just because it won't filter exactly what you want:
Get-ADUser -Filter {SamAccountName -like 's*'} |
where { ($_.SamAccountName -match "[Ss]{1}[0-9]{5}[NnDd]{1}") }
will eliminate all the accounts that don't start with "s" up front, cutting down on what's left to filter in Where-Object.
