how to integrate this function

i am little confused with the integration here.
my function is,

f ( z ) = sin ( a*z) * dirac_delta ( z - b )

i need to integrate f (z) with respect to z
within limits -100 to 0. a and b are constants.

can i write
dirac_delta ( z-b ) = abs (a) * dirac_delta (a*( z-b) ) ?
and then evaluate the integral ?
if this is not correct then how to solve the integral ?
many thanks for help.
