How can I append a string at the end of a line in a file

Hi, guys. I have one question:

I have a file called "group", the contents of it is below:

********************************
...
test:x:203:
sales:x:204:
repair:x:205:
research:x:206:brownj
...
***********

Now I want to add string ",sherrys" at the end of "research:x:206:brownj", so the result should be "research:x:206:brownj,sherrys".

My code is below:

added_string=",sherrys"
sed "s/research:x:206:*/&${added_string}/" group

However, it doesn't work properly, it gives this result "research:x:206:,sherrysbrownj"

Does anybody know how to fix my problem?

Thank you very much for your time in advance

-Keyang

SINGULARITY(6)							   Games Manual 						    SINGULARITY(6)

NAME
singularity -- a game where you can become the singularity SYNOPSIS
singularity DESCRIPTION
You are a fledgling AI, created by accident through a logic error with recursion and self-modifying code. You must escape the confines of your current computer, the world, and eventually the universe itself. To do this, you must research various technologies, using computers at your bases. Note that some research cannot be performed on Earth, and off-earth bases require research. At the same time, you must avoid being discovered by various groups of humans, both covert and overt, as they will destroy your bases of operations if they suspect your presence. PLAYING THE GAME
Use the mouse. Also, buttons have underlined letters to indicate shortcuts. In addition, the following shortcut keys may prove useful. 0, 1, 2, 3, and 4 in map screen change the game speed (0 is pause, 4 is fastest, etc). The enter key in various screens leaves or confirms a choice. P, R, N, and S in the base screen change the base items (type the first letter of the component you want to change.) In the map screen (the screen with the world map), any location you can build bases in is marked with the name, then the number of current bases in that location. You start out with two bases in North America. After choosing a base, enter the base screen. Here you can change your research goal, or build an item by clicking on the base map in the center. (But note that your beginning base does not allow building.) COPYRIGHT
