+====================
+Sequence Check Digit
+====================
+
+This module was written to configure check digits on sequences added on the end.
+It is useful as a control of the number on visual validation.
+
+It is useful when some manual checks are required or on integrations.
+The implemented codes can avoid modification of one character and flip of
+two consecutive characters.
+
+Usage
+=====
+
+* Access sequences and configurate the model to use.
+* The model will check if the format of prefix, suffix and number is valid
+* Implemented algorithms
+    * Luhn: [0-9]*
+    * Damm: [0-9]*
+    * Verhoeff: [0-9]*
+    * ISO 7064 Mod 11, 2: [0-9]*
+    * ISO 7064 Mod 11, 10: [0-9]*
+    * ISO 7064 Mod 37, 2: [0-9A-Z]*
+    * ISO 7064 Mod 37, 36: [0-9A-Z]*
+    * ISO 7064 Mod 97, 10: [0-9A-Z]*
