The integrity of an IMO number can be verified by its check digit, which is the rightmost digit. This is done by multiplying each of the leftmost six digits by a factor corresponding to their position from right to left, and adding those products together.
Rage (written as Getting It On; the title was changed before publication) is the first novel by Stephen King published under the pseudonym Richard Bachman in 1977. It was collected in 1985 in the hardcover omnibus The Bachman Books. The novel describes a school shooting, and has been associated with actual high school shooting incidents in the 1980s and 1990s. As a result, King has allowed the novel to fall out of print.
It has been suggested that it was written for Thomas' dying father, although he did not die until just before Christmas 1952. It has no title other than its first line, Do not go gentle into that good night, a line which appears as a refrain throughout. Its other refrain is Rage, rage against the dying of the light. The poem currently remains under copyright, but was made publicly available here [1] at poets.org (with the copyright holder's permission).
