in matlab nested if statement not working properly?

if code==0411106200445
     open('product1.txt');

elseif code==506002830376
      open('product2.txt');
elseif code==9781234567897
      open('product3.txt');
elseif code==987654321098
      open('product4.txt');
else 
     open('product5.txt');
end

when my result coming to this loop it opened always last txt file(product5.txt).. not working for other results... why?

It is working properly. None of your code values ever equal any of those integers. Your code is an integer isn't it? It's not a double or string is it? What does it say the value of code is when you step through it in the debugger? You are using the debugger aren't you?
