The check digit for a SEDOL is chosen to make the total weighted sum of all seven characters a multiple of 10. The check digit is computed using a weighted sum of the first six characters. Letters have the value of 9 plus their alphabet position, such that B = 11 and Z = 35.
The integrity of an IMO number can be verified using its check digit. The checksum of an IMO ship identification number is calculated by multiplying each of the first six digits by a factor of 7 to 2 corresponding to their position from right to left. The rightmost digit of this sum is the check digit. Example for IMO 9074729:
Since India became independent in 1947, the postal service continues to function on a nationwide basis, providing a variety of services. The structure of the organization has the directorate at its apex; below it are circle offices, regional offices, the superintendent's offices, head post offices, sub-post offices and branch offices.
Assuming narrow elements are one unit wide and wide elements are two units, the average digit is 7.8 units. This is better than codes with a larger repertoire like Codabar (10 units) or Code 39 (11 units), but not quite as good as interleaved 2 of 5 (7 units). The non-binary symbology Code 128 uses 5.5 units per digit (11 units per digit pair).

Originally developed in 1929 by Kiyoshi Mori, the 10th and latest edition of this system was published in 2014.
The check digit calculation is as follows: each position is assigned a value; for the digits 0 to 9 this is the value of the digits, for the letters A to Z this is 10 to 35, for the filler < this is 0. The value of each position is then multiplied by its weight; the weight of the first position is 7, of the second it is 3, and of the third it ...
Telephone numbers in Ireland are part of an open numbering plan that allows variations in number length. The Irish format is similar to systems used in many parts of Europe, notably the Netherlands, Sweden, Germany, Belgium and France, where geographical numbers are organised using a logic of large regional prefixes, which are then further subdivided into smaller regions.
