Category:CS1 errors: DOI

It is used to build and maintain a list or lists of pages—primarily for the sake of the lists themselves and their use in article and category maintenance. It is not part of the encyclopedia's categorization scheme.

More information:

This category is hidden on its member pages—unless the corresponding user preference (Appearance → Show hidden categories) is set.
These categories are used to track, build and organize lists of pages needing "attention en masse" (for example, pages using deprecated syntax), or that may need to be edited at someone's earliest convenience.
These categories also serve to aggregate members of several lists or subcategories into a larger, more efficient list (discriminated by classifications).
Typically, tracking categories are automatically populated by templates invoked in pages or by the MediaWiki software (see Special:TrackingCategories for an overview of the latter).

Administrators: Please do not delete this category as empty!
This category may be empty occasionally or even most of the time.

This is a tracking category for CS1 citations that have |doi= errors.

Many (although not all) errors in the category can automatically be fixed by clicking here to activate User:Citation bot.

Check |doi= value

When Citation Style 1 and Citation Style 2 templates contain |doi=, a test is done to see if the prefix portion of the DOI value is correctly formatted and has what appears to be a valid registrant code. A proper DOI prefix begins with the 10. directory indicator. The remaining portion of the prefix is a string of digits and the dot character which form the registrant code. When the directory indicator is 10., the CS1|2 templates test for a valid registrant code. Valid registrant codes:

must be composed of digits
must be in the range:
- 1000–9999
- 10000–49999
may have one or more subcodes that begin with a dot followed by digits (1000.10)
must not be 5555 (invalid/temporary/test)

Additionally, the |doi= value is checked to make sure that it does not contain spaces, en dashes, does not end with punctuation. Further validation of the DOI is not performed.

Do not include the https://doi.org/ scheme and domain name from a URL. A proper |doi= value looks like |doi=10.1103/PhysRevLett.80.904.

To resolve this error, ensure that the |doi= value is correct.

In very rare cases, publishers have released works with a DOI deviating from the standard form. If you are certain that such a non-conforming DOI truly corresponds to the published work, then you can add accept-this-as-written markup around the identifier to suppress the error message. (Do not use this markup for DOIs, which are inactive rather than non-conforming. Instead, use |doi-broken-date= for them.)

Pages with this error are automatically placed in Category:CS1 errors: DOI.^[a]

Help desk

|doi-broken-date= requires |doi=

When |doi-broken-date= is used in a CS1|2 template, |doi= (with value) must also be present.

To resolve this error, either add the missing DOI or remove the 'broken' parameter.
