works for me when single quoted:
Code:
sed '/^\s*\r$/d' file
E3C5X5
DCL4
DICER
CAS1A
CAS2A
APE
T2BA
ENDOA

Alternate methods: use the <CTRL>-V lead-in for <CR>:sed /^\s*^M$/d file or the shell construct $'\r': sed /^\s*$'\r'$/d file.

Maybe as the MAC has <CR> as a line terminator, try sed '/^\n$/' file.
