This seems working on your as-is data:

DATA TEST;

     INFILE CARDS TRUNCOVER;

     INPUT VAR $100.;

     DIGITS=prxchange('s/^\d+\D+|\D+$//o',-1,var);

     CARDS;

43534-PP - ABCDEF 150 ABC ABCD

07052-TT - ABCD 100 ABCDEFG

83092-DD -   ABCDEFG 540 ABCDEFRGTH

Or just use scan, nice one xia keshan.

Alternatively, without perl:

data test;

  infile cards truncover;

  input var $100.;

  digits=compress(scan(var,3,'-'),' ','a');

cards;

43534-PP - ABCDEF 150 ABC ABCD

07052-TT - ABCD 100 ABCDEFG

83092-DD -   ABCDEFG 540 ABCDEFRGTH

;

run;

DATA TEST;

     INFILE CARDS TRUNCOVER;

     INPUT VAR $100.;

     DIGITS=scan(var,2,,'kd');

     CARDS;

43534-PP - ABCDEF 150 ABC ABCD

07052-TT - ABCD 100 ABCDEFG

83092-DD -   ABCDEFG 540 ABCDEFRGTH

Nice. Never see 'kd' option in SCAN(). Thanks for sharing!

Well in this case, depending on OP's rules, DIGITS=scan(var,-1,,'kd'); will also be OK.
