I think I'm interested in something more general. I'm trying to capture the first number after the hyphen (wherever the hyphen may be and without any knowledge of what comes after the number following the hyphen).
However, for right now this should work (note that a negative sign is needed to grab from the back of the string): 
gen y=substr(d,-1,1)



 gen y = substr(x,1,1)
 destring y, replace
   should do it.
