![]() ![]() ![]() The check digit: one Arabic numeral providing a means of validating the recording and transmission accuracies of the owner code and serial number. The GRID Checksum Calculator can be used to calculate the checksum portion of the GRID based on the Issuing Organization Number (ION) and Registration Donor.The serial number: six Arabic numerals, left at owner‘s or operator‘s option,.J for detachable freight container-related equipment,.The equipment category identifier: one capital letter as follows:.The owner prefix (BIC code): three capital letters of the Latin alphabet to indicate the owner or principal operator of the container,.The check digit is calculated from all the preceding digits. The identification system provides uniform international identification of containers, in documentation and in communication associated with the movement of containers from door to door. All GTINs need a check digit, and this is the last digit of the number. MD5 Checksum Calculator is a small, simple utility for calculating and comparing the MD5 checksum values of specified files. All characters shall be of proportionate width and thickness, they shall be durable and in a colour contrasting with that of the container. The letters and numerals of the owner code, equipment category identifier, serial number and check digit shall be not less than 100 mm (4 in) high. How is a check digit calculated?Īs the check digit is calculated using an algorithm that takes into account both the BIC code and serial number, it is imperative that the check digit be modified when containers are re-marked with a different BIC code. This allows operators, terminals, depots and other parties in the supply chain to automatically validate container numbers and easily identify incorrect container numbers introduced through a data-entry error or an erroneous OCR (optical character recognition) reading. ![]() The checksum is simple, just an XOR of all the bytes between the and the (not including the delimiters themselves), and written in hexadecimal. The container check digit provides a means of validating the transmission accuracy of the owner/operator code and serial number. This is a simple calculator to compute the checksum field for the MediaTek / ETEK chipset's command extensions to the NMEA protocol. You have the possibility to calculate 25 check digits at once if the serial number are sequential Enter the first six digits of the ending serial number. ![]()
