Input Validation of comma separated values

Hello all,

I am working on a script and have the first part solved of numerical input validation. Below the code validates that the input is a numerical value between 100 and 1000. If not, it errors out. Now I need to be able to read values separated by a comma. For example, instead of my input being let's say 105, I'd like for the input validated to be more like 105,106,500. How can I achieve this masters of scripting?

Current code for custom function:
Code:
get_info_check ()
{
echo
echo "Which INFO check would you like to run?"
echo "The valid range is 100-999."
print -n "Enter INFO number : "
read INFO_CHK
#INPUT VALIDATION HERE!!!
if [[ "$INFO_CHK" != +([0-9]) ]]
  then
      echo
      echo "ERROR: You must enter a valid number!!"
      get_info_check
elif [ "$INFO_CHK" -ge 100 -a "$INFO_CHK" -le 999 ]
  then
     echo "GOOD JOB!!!"
else
     echo
     echo "ERROR: Valid range is 100-999!!"
     get_info_check
fi
}

NAME
XmRepTypeRegister -- A representation type manager function that registers a representation type resource SYNOPSIS
#include <Xm/RepType.h> XmRepTypeId XmRepTypeRegister( String rep_type, String *value_names, unsigned char *values, unsigned char num_values); DESCRIPTION
XmRepTypeRegister registers a representation type resource with the representation type manager. All features of the representation type management facility become available for the specified representation type. The function installs a forward type converter to convert string values to numerical representation type values. When the values argument is NULL, consecutive numerical values are assumed. The order of the strings in the value_names array determines the numerical values for the resource. For example, the first value name is 0 (zero); the second value name is 1; and so on. If it is non-NULL, the values argument can be used to assign values to representation types that have nonconsecutive values or have dupli- cate names for the same value. Representation types registered in this manner will consume additional storage and will be slightly slower than representation types with consecutive values. A representation type can only be registered once; if the same representation type name is registered more than once, the behavior is unde- fined. The function XmRepTypeAddReverse installs a reverse converter for a registered representation type. The reverse converter takes a represen- tation type numerical value and returns the corresponding string value. If the list of numerical values for a representation type contains duplicate values, the reverse converter uses the first name in the value_names list that matches the specified numeric value. For example, if a value_names array has cancel, proceed, and abort, and the corresponding values array contains 0, 1, and 0, the reverse converter will return cancel instead of abort for an input value of 0. rep_type Specifies the representation type name. value_names Specifies a pointer to an array of value names associated with the representation type. A value name is specified in lowercase characters without an Xm prefix. Words within a name are separated with underscores. values Specifies a pointer to an array of values associated with the representation type. A value in this array is associated with the value name in the corresponding position of the value_names array. num_values Specifies the number of entries in the value_names and values arrays. RETURN
Returns the identification number for the specified representation type. RELATED
