Ungolfed + some annotations:

; reverse number and rotate "6" & "9"
; and do some counts (c when "6" or "9" and d when != "0689")
parse reverse a [

| "8"
| skip (++ d)
]
]
print rejoin [
b either all [
d = 0 ; only has 0689 digits
c > 0 ; must have at least one "6" or "9"
a != b ; not same when reversed
a/1 != #"0" ; does not "end" with zero
