somebody check pls

Ringcode is incomplete

Sorry. I somehow entered completely wrong data.

Mastering code: Sony DADC   A0100882104-B911 16
Mastering SID Code: IFPI L557
Mould SID: A01
and there is another  text below this, closer to center of UMD, i don't know where to put that: IFPI L556 Sony DADC

This is a 2 layer disc, so you need to submit the ringcode matrix for both layers using the following scheme:
Layer #: Mastering Code | Mastering SID | Toolstamp | Mould SID
L1: Mastering Code L1 Missing | IFPI L557 | A01 | Mould SID data side missing
L2: Sony DADC   A0100882104-B911 16 |  IFPI L556 |  Toolstamp L2 missing

You could always supply a scan or photo if you are unsure.
