ICAP::calculate_icap ICAP::calculate_bban "0x000072B1A5F4864C2BA2b14471e48Cc118264794"
  #   => "XE43 9JD3 UD9B FMRC RDS1 IC6B S5MT AQ38"
ICAP::extract_address "XE43 9JD3 UD9B FMRC RDS1 IC6B S5MT AQ38"
  #   => "0x000072B1A5F4864C2BA2b14471e48Cc118264794"
ICAP::check_checksum? "XE43 9JD3 UD9B FMRC RDS1 IC6B S5MT AQ38"
  #   => true
ICAP::calculate_iban_checksum "XE", "09JD3UD9BFMRCRDS1IC6BS5MTAQ38"
  #   => 43
ICAP::calculate_bban "0x000072B1A5F4864C2BA2b14471e48Cc118264794"
  #   => "9JD3UD9BFMRCRDS1IC6BS5MTAQ38"
