I believe you meant:

111000001

That's 449 in binary format. The first digit's place (on the right) stands for the 1's places. So we got powers of 2 looking like this:

256 128 64 32 16 8 4 2 1

Moving from right to left, there is a 1 in the 1's place, a 0 in the 2's place, a 0 in the 8's place, a 0 in the 16's place, a 0 in the 32's place, a 1 in the 64's place, a 1 in the 128's place, and also a 1 in the 256's place.

Thus, adding those values together:

1 + 64 + 128 + 256 (or if you wanted to go the other way, 256 + 128 + 64 + 1)

we get the value of 449.

On the other hand, if we use the numbers you came up with:

0011 0100 0011 0100 0011 1001

we get a 1 in the 1's place, a 0 in the 2's and 4's place, a 1 in the 8's place, a 1 in the 16's place, a 1 in the 32's place, a 0 in the 64's place, a 0 in the 128's place, a 0 in the 256's place, a 0 in the 512's place, a 1 in the 1024's place, a 0 in the 2048's place, a 1 in the 4096's place, a 1 in the 8192's place, a 0 in the 16384's place, a 1 in the 32768's place, a 1 in the 65536's place, a 0 in the 131072's place, and last of all, a 0 in the 262144's place, we add up the numbers:

1 + 8 + 16 + 32 + 1024 + 4096 + 8192 + 32768 + 65536

and get 111673, which is nothing close to 449.

Now here is 450 in binary format:

111000010
