Use SharePoint Column Validation.

Edit the column and paste below formula in Column Validation Formula. You could even write the custom error message:

=AND(IF(ISERROR(FIND("0",Title)),TRUE),IF(ISERROR(FIND("1",Title)),TRUE),IF(ISERROR(FIND("2",Title)),TRUE),IF(ISERROR(FIND("3",Title)),TRUE),IF(ISERROR(FIND("4",Title)),TRUE),IF(ISERROR(FIND("5",Title)),TRUE),IF(ISERROR(FIND("6",Title)),TRUE),IF(ISERROR(FIND("7",Title)),TRUE),IF(ISERROR(FIND("8",Title)),TRUE),IF(ISERROR(FIND("9",Title)),TRUE)
