When calling grep benzylicus oddb_calc.xml | grep -v SUBSTANCE_NAME we find 16 lines where the substance was not recognized correctly, e.g. <CORRESP>conserv.: alcohol benzylicus 18 mg, aqua ad iniectabilia q.s. ad solutionem pro 2 ml</CORRESP>
Reworking to handle lines starting with Solvens to make them parse the containing substance and setting a "corresp" if this is not possible. E.g. Redimune 3 g, Trockensubstanz mit Solvens which has Solvens: natrii chloridi solutio 9 g/L 100 ml.
Unit-Tests work. Waiting for oddb2xml --calc to finish to compare all items with the previous version.
The EAN13 7680556740075 has a wrong corresp field, which currently looks like
  <ARTICLE>
    <GTIN>7680556740075</GTIN>
    <NAME>Caverject DC 20, Injektionspräparat</NAME>
    <PKG_SIZE>2</PKG_SIZE>

    <GALENIC_FORM>Injektionspräparat</GALENIC_FORM>

      <COMPOSITION>
        <CORRESP>alprostadilum 20 µg, alfadexum, lactosum anhydricum,
natrii citras dihydricus, conserv.: alcohol benzylicus 4.45 mg, aqua

reconstituta</CORRESP>
        <SUBSTANCES/>
      </COMPOSITION>
    </COMPOSITIONS>
  </ARTICLE>
Something odd seems to happen hear, as CompositionParser.new.composition.parse_with_debug of the source string gives a correct result. 
The two Caverject are the only product which start their "Zusammensetzung" with "Solvens:", which is semantically just wrong! Therefore adding a fix, which transforms Solvens: alprostadilum by alprostadilum
Pushed commit Fix Caverjet by eliminatins semantically wrong leading "Solvens:"
For EAN13 7680235330306 "Solu-Cortef 100 mg, Injektions-/Infusionspräparat" I have now instead of
      <COMPOSITION>
        <CORRESP>conserv.: alcohol benzylicus 18 mg, aqua ad iniectabilia q.s. ad solutionem pro 2 ml</CORRESP>
        <SUBSTANCES/>
