I was wondering if there is a way to use the verify function with my check as a numeric interval. For example,
if verify(Age, check) ne 0 then put 'not allowed';

No, because it's a character function, not numeric.
There are relatively easy other ways, but I suspect you're also going to extend this beyond this specific example.
*check for integers 1 to 10; if age in (1:10) then...; *check for values 1 to 10, including endpoints; if 1<=age<=10 then...;

For some uses a format might work to create output similar to what you want.
Proc format library=work; value validage 1 - 10 ='Valid' other = 'Invalid'; run; data example; input Age; put Age= age validage.; datalines; 1 3 . 15 ; run;
This approach is fairly flexible if you have similar variables that all use the same range for valid values. It will also work for character values with the proper format.
Depending on what is done with the information, such as a step later to recode to value, then perhaps an informat might be appropriate to read and recode at one step.
