validator = Argentinian::Validations::Cbu.new(valid_cbu)
validator.valid? #=> true
validator.validate! #=> "2850590940090418135201"

Usage in Rails

It is very useful to use the custom validators provided by Rails:

# app/validators/cbu_validator.rb
class CbuValidator < ActiveModel::EachValidator
  def validate_each(record, attribute, value)
    validator = Argentinian::Validations::Cbu.new(value)
    record.errors.add(attribute, validator.errors.first) unless validator.valid?
  end
end

And then in your model:

# app/models/my_model.rb
class MyModel < ApplicationRecord
  validates :number, cbu: true
end

Development

After checking out the repo, run bundle install to install dependencies.
