public final class ECIndexNumberValidator extends Object implements Serializable
EC index number validation.

The European Community index number is a unique nine-digit identifier that is assigned to hazardous chemical substances.
For example, the EC index number of lithium is 003-001-00-4

The Index number for each substance is in the form of a digit sequence of the type ABC-RST-VW-Y.
ABC corresponds to the atomic number of the most characteristic element or the most characteristic organic group in the molecule.
RST is the consecutive number of the substance in the series ABC.
VW denotes the form in which the substance is produced or placed on the market.
Y is the check-digit. Check digit calculation is based on modulus 11 with digits being weighted based on their position (from left to right).
