That is indeed useful, thanky.
In your case, look at the numbers, 7,8,& 9 have the same chemical shift, 0.871 ppm and will therefore appear as 1 signal. Protons 10 & 11 have the same shift, 1.282ppm, therefore will appear as 1 signal.
Same for 12 & 13, 15 & 16 and 17, 18 & 19, 20, and 21 & 22.
Six distinct groups of signals. And one by itself.
