Try putting the MRN values into a temporary table. Then use a join to get the ones you want. Something like

CREATE TABLE #MyTemp (MRN INT);
INSERT INTO #MyTemp (MRN) VALUES 
(614133),
(695588),
(755580),
(763133),
(773174),
(785829),
(794734),
(902446),
(932324),
....
;
SELECT DISTINCT MRN FROM w_enc 
INNER JOIN ON #MyTemp ON w_enc.MRN = #MyTemp.MRN;

OP wants the missing mrn's, so select should be something like:

select mrn
  from #mytemp as a
 where not exists(select 1
                    from w_enc as b
                   where b.mrn=a.mrn
                 )
;
