How to generate random unique Alphanumeric six digit number from sequence value

User_V6AO3Jan 28 2022

Hi All,
I have a requirement to generate random unique Alphanumeric six digit number from sequence value.Could you please help..
E.g sequence value = 65918362 (which will be generating unique value increment by 1)
but from that seq i have to generate for first 4 digit,it should be unique character value(no special charcater) and other 4 digit will remain same like sequence value.
---------------------
I have used below func like
Select CHR(TO_NUMBER(SUBSTR(65918362, 1, 2))) ||CHR(TO_NUMBER(SUBSTR(65918362, 3, 2)))|| SUBSTR(65918362, 5) from dual;

Output: A**[**8362---Which is not correct ..because upto 90 it will return AZ8362.

So I need the output like AB8362,BBthen4digit no(i.e every time it should be unique).
Please help me..
Thanks,
Raghu
