korn shell: check the content of a string of a variable

hello,

i have a variable which should have following content :

var="value1"
or
var="value2"
or
var="value2:[digit][digit]*" # example: value2:22

how can i check :
- if the content is ok (value1 / value2* )
- the two options of "value2"

when content is example "value2:22" , i want to split it in "part1" and "part2" , like "value2", "22". for spliting i will use "awk"

is is possible to do this with "case" (with ERE) ?

Code:
case "${var}" in
  "value1" ) ...
  value2* )  case "${var}" in
                    value2 ) ...
                    value2:* ) ...
...
esac

split :
Code:
echo ${var}" | awk -F":" '{ print $1, $2 }' | read part1 part2

regards
