How many double bonds does TR006 have and is it carcinogenic?
label = '+' mean molecules are carcinogenic; label = '-' means molecules are non-carcinogenic; double bond refers to bond_type = ' = ';
SELECT COUNT(T1.bond_id), T2.label FROM bond AS T1 INNER JOIN molecule AS T2 ON T1.molecule_id = T2.molecule_id WHERE T1.bond_type = '=' AND T2.molecule_id = 'TR006' GROUP BY T2.label
