replace numbers in records

hello every one
I have file with following records

Code:
begin
ASX120016719
ASX190006729
ASX153406729
ASX190406759
ASX180006739
end

for each record there is ASX word then 9 digits after it (NO spaces included)
what i want is to :

1- skip ASX
2-skip first 2 digits after ASX word
3- check digits 3-5, if all zeros then ok, go to next record
4- if any digit from 3 to 5 is a number then check digit 8
if digit 8 is 1 or 2 then make digits 3-5 zeros
if digit 8 is NOT 1 or 2 then ok go to next record

According to the above records, the output should be:
Code:
begin
ASX120006719
ASX190006729
ASX150006729
ASX190406759
ASX180006739
end

i tried sed command but i could not figure the right syntax..

set_color(1)							       fish							      set_color(1)

NAME
set_color - set_color - set the terminal color set_color - set the terminal color Synopsis set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR] Description Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple, cyan, white and normal. o -b, --background Set the background color o -c, --print-colors Prints a list of all valid color names o -h, --help Display help message and exit o -o, --bold Set bold or extra bright mode o -u, --underline Set underlined mode o -v, --version Display version and exit Calling set_color normal will set the terminal color to whatever is the default color of the terminal. Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey font color, while set_color --bold white will result in a white font color. Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator. set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of ncurses and recompile fish against it in order to fix this issue. Version 1.23.1 Sun Jan 8 2012 set_color(1)
