routines in package
org.apache.commons.validator.routines.checkdigit
do not validate the input for length or syntax. This is documented in
package-info
Respected this idea I change CASNumberCheckDigit and ECNumberCheckDigit.
And provide CASNumberValidator and ECNumberValidator which validates the syntax.
I also add a Validator for ECIndexNumber, a unique nine-digit identifier that is assigned to hazardous chemical substances.
