EDIT:

shorter code:

my $string = "{'totalResultsCount':71-24,'securityList':[{'cusip':'91%
+279-6.H:Y8','issueDate':'2016-06-02T00:00:00','securityType':'Bill'}"
+;
$string =~ s/.*('cusip':'([\w\-\$\.\%\:]+)').*/$2/g;
print "first is : $string \n" for $string =~ s/\W+//g;

EDIT: changed print "first is : $string \n" if $string =~ s/\W+//g; to print "first is : $string \n" for $string =~ s/\W+//g;
