Luhn algorithm. The Luhn algorithm or Luhn formula, also known as the " modulus 10" or "mod 10" algorithm, named after its creator, IBM scientist Hans Peter Luhn, is a simple check digit formula used to validate a variety of identification numbers. It is described in US patent 2950048A, granted on 23 August 1960. [1]
The Luhn mod N algorithm is an extension to the Luhn algorithm (also known as mod 10 algorithm) that allows it to work with sequences of values in any even-numbered base. This can be useful when a check digit is required to validate an identification string composed of letters, a combination of letters and digits or any arbitrary set of N ...
If the remainder is equal to 0 then use 0 as the check digit, and if not 0 subtract the remainder from 10 to derive the check digit. A GS1 check digit calculator and detailed documentation is online at GS1's website. [5] Another official calculator page shows that the mechanism for GTIN-13 is the same for Global Location Number/GLN. [6]
Hans Peter Luhn (July 1, 1896 – August 19, 1964) was a German-American [2] researcher in the field of computer science and Library & Information Science for IBM, and creator of the Luhn algorithm, KWIC (K ey W ords I n C ontext) indexing, and selective dissemination of information ("SDI"). His inventions have found applications in diverse ...
MSI barcode for the number 1234567 with Mod 10 check digit. MSI (also known as Modified Plessey) is a barcode symbology developed by the MSI Data Corporation, based on the original Plessey Code symbology. It is a continuous symbology that is not self-checking. MSI is used primarily for inventory control, marking storage containers and shelves ...
The International Mobile Equipment Identity (IMEI) [1] is a numeric identifier, usually unique, [2][3] for 3GPP and iDEN mobile phones, as well as some satellite phones. It is usually found printed inside the battery compartment of the phone but can also be displayed on-screen on most phones by entering the MMI Supplementary Service code *#06 ...
Italy will offer an extra 10,000 migrant work visas next year for people who look after old people and the disabled, the government said on Wednesday, as it adopted a new package of migration rules.
The first table, d, is based on multiplication in the dihedral group D 5. [7] and is simply the Cayley table of the group.Note that this group is not commutative, that is, for some values of j and k, d(j,k) ≠ d(k, j).
