Why my regular expression doesn't return any matches?

Hi, I'm trying to build a regular expression that later on I can parse all the values from a string as follows:

VB

FFD:000D6F0002542F8D,531F,-82,FF
FFD:000D6F00015D518F,B643,-70,FF
FFD:000D6F0000D5493B,9915,-71,FF
FFD:000D6F00015D5CE1,9F69,-83,FF
FFD:000D6F000257F6CF,4D1F,-60,FF
SED:000D6F0000BA1A7E,63AA,-70,FF
FFD:000D6F0000D5F442,7CDE,-84,FE
FFD:000D6F0000BA19B9,0000,-59,FF
FFD:000D6F00024D00E5,D63E,-62,FF
FFD:000D6F0000D5F277,0290,-81,FF
FFD:000D6F0000D57E63,3B1F,-84,FB
FFD:000D6F000257F5EC,B2BE,-56,FF
FFD:000D6F00015CA322,9EA6,-68,FF

RegEx that I've built so far:
[[(COO)][(FFD)][(RFD)][(MED)][(SED)][(ZED)]]+:[0-9[A-F]]{16}+,+[0-9[A-F]]{4}+,+[(\-\d)]+,+[0-9[A-F]]{2}

This website has been very helpful testing my expression in java:

It looks like it's finding all expressions but it's not returning any matches why is that?

Thank you very much.

If you want to extract numbers from the string? try \d+

Thank you very much Peter for your solution. It's very nice to see visually the regex. Just to complement the solution: to make easier to parse the string I grouped every element with parenthesis.

final: (COO|FFD|RFD|MED|SED|ZED):([0-9A-F]{16}),([0-9A-F]{4}),(\-\d+),([0-9A-F]{2})

Your regex has some syntax errors. Like []{16}+ and some logic errors...

See this one:

(COO|FFD|RFD|MED|SED|ZED):[0-9A-F]{16},[0-9A-F]{4},\-\d+,[0-9A-F]{2}

Now to explanations...

(COO|FFD|RFD|MED|SED|ZED)

- find one of these character sequences

[0-9A-F]{16}

- 16 characters from the hexadecimal range

\-\d+

- a minus (-) sign and at least one digit
