Absent Chiral Flag
-     Checker searches for Absolute chiral flag attached to the molecule if the molecule is chiral and all stereo centers are precisely marked. 
-     Fixer adds chiral flag (Absolute) to the molecule (addchiralflag). 
Example :
| Absent Chiral Flag Checker (absentchiralflag) | Warning: | Fix | 
| Add Chiral Flag (addchiralflag) | ||
| Detect Absent Chiral Flag |      |      |
