What about a Dictionary that you will fill like

dict.Add(CheckType.Form, DoSomething);
dict.Add(CheckType.TempDate, DoSomethingElse);
...

a decomposition of your value

flags = Enum.GetValues(typeof(CheckType)).Where(e => (value & (CheckType)e) == (CheckType)e).Cast();

and then

foreach (var flag in flags)
{
   if (dict.ContainsKey(flag)) dict[flag]();
}
