It appears you only have 4 time fields.  

>From the crontab man page:

Each line has five time and date fields, followed by a user name if this
is  the  system  crontab  file,  followed  by  a  command.

Also, your time selection could be written 0-23/2

For example, ‘‘0‐23/2’’ can be used in the hours field to specify
command execution every other hour (the alternative in the V7 
standard  is ‘‘0,2,4,6,8,10,12,14,16,18,20,22’’)
