Use SCAN() function with a index of -1.

want = scan('Kwstala/416544/95ewS661204/9245',-1,'/');

You can use those PRX functions to get the target striong as well the postion:

data test;
	want_scan = scan('Kwstala/416544/95ewS661204/9245',-1,'/');
	ptn=prxparse('/(?<=\/)\d+$/');
	pos=prxmatch(ptn,'Kwstala/416544/95ewS661204/9245');
	want_prx=prxchange('s/(\S+)\/(\d+$)/\2/',-1,'Kwstala/416544/95ewS661204/9245');
run;

data _null_;
	want_scan ='Kwstala/416544/95ewS661204/9245';
	pos=findc(want_scan,'/','b');
	put pos= ;
run;

Use CALL SCAN()
this will trll you the position and length of the selected "word".
For the last "word" try -1 in :
Call scan( big_string, -1, pos, len, '/' ) ;
