Why not check for the empty string using a Required validation attribute alongside your RegularExpression attribute?

[Required(ErrorMessage = "This field is required")]
[RegularExpression(@"\b(0?[0-9][0-9][0-9])\b", 
                  ErrorMessage = "BEI Code should be Only three Chracter Length!")]

Thanks Jamie, yes I tried that but some reason my Required filed is not working properly.. Instead of This field is required I am getting the message for Empty '{PropertyName}' should not be Empty.. I dont know why I am getting this message?
