Select from SubQuery

I have code that is inserting records into a temp table, Then using that those records in a second query:
select distinct(CASE_NO) into #Temp_Case_Attach_nlto
from Case_Attachments
 where CASE_NO in
(select CASE_NO from Case_Actions
where CASE_NO in (select CASE_NO from Case_Main
where STARTED >='2015-06-01' and STARTED <= '2015-06-30'))
and DESCRIPTION like '%nlto%' --(43 row(s) affected)

select * from #Temp_Case_Attach_nlto
where CASE_NO not in
      (select distinct(CASE_NO) from Case_Attachments
  where CASE_NO in
(select CASE_NO from Case_Actions
where CASE_NO in (select CASE_NO from Case_Main
where STARTED >='2015-06-01' and STARTED <= '2015-06-30'))
and DESCRIPTION like '%nov%') -- 41   include this first section with the and
and CASE_NO not in
      (select CASE_NO from Case_Main
      where STATUS = 'UNFOUNDED')      --41  ---Use this number for cases resolved voluntarily
      drop table #Temp_Case_Attach_nlto

I want to create a query that will allow me to do the second query getting a count without using a temp table something like:
SELECT Distinct COUNT(*)
from
(SELECT Distinct CASE_NO
                   FROM Case_Attachments
                         Where DESCRIPTION like '%nlto%'
                         and CASE_NO in
                 (Select CASE_NO from Case_Actions
                  Where CASE_NO in (Select CASE_NO from Case_Main
                    Where STARTED >= '2015-06-01' and STARTED <= '2015-06-30')))
   Where CASE_NO not in
      (select distinct(CASE_NO) from Case_Attachments
  where CASE_NO in
(select CASE_NO from Case_Actions
where CASE_NO in (select CASE_NO from Case_Main
where STARTED >='2015-06-01' and STARTED <= '2015-06-30'))
and DESCRIPTION like '%nov%')
and CASE_NO not in
      (select CASE_NO from Case_Main
      where STATUS = 'UNFOUNDED')                       

HOWEVER, It does not like the where clause after the select from.
