Tragedy...one post better then other...total misunderstanding.
One man need help, another one gives false info - wonderfull help , and thanks is given for false info.
So, doctore, how we can respect such answers ?
I have respect for all people, but it seems some people like wear crown on their heads and acts like Gods.
Stupid understanding of reality - all i can say.

P.S. For topicstarter - your cas uses ews4 system, so isn given in 4th post is wrong.
Your cas is crypto - u can not get isn from this eeprom. Read it from MSD802.
P.S.S. Im in Poland , write PM

This is the encrypted ISN, stored in the CAS:

Code:

1C CD BD 75 B8 45 51 57 7D AB 0D 9B 28 AA 50 2A

.
In order to get the plaintext ISN, stored in the DME, you'll either have to read it directly from the DME or, if you need it to be calculated from the CAS, read and post all pages of a working key.
