Totals for footer sql server query

below is my working query thus far.

I am missing a final piece which is a select with special concantonation in front of the current final select to ADD all the CHECK NUMBERS together in otherwords check number 1003, 1002, 1000, and 1001 would show in the result as 0000004006
Also - right now with the current code (working) my bottom line of output is  
000000624168510

so now with the example I gave it would read like this:

0000004006000000624168510
Then if there were 4 checks (as in the example it will appear:

                                       
1EOF 00004                    00000040060624168510

finally - THE TRAILING ZERO ON 00000040060624168510 NEEDS TO MOVE AT THE END OF THE CHECK NUMBERS ADDED TOGETHER THUS

1EOF 00004                    00000040060062416851

I wish I could assign DOUBLE TRIPLE etc points for this but I can't  Thank you so much IN ADVANCE :)
