10.1046 Blackwell Publishers. Details to follow.
10.1055 G. Thieme Verlag (Synthesis).Structure: s-YEAR-XXXXX, where XXXXX is a 5-digit article code.
10.1063 American Institute of Physics. The DOI of recent articles (example: http://dx.doi.org/10.1063/1.1385363) can be found on the online abstract of the paper. However, AIP offers a very convenient alternative (a kind-of "OpenURL avant-la-lettre"): http://link.aip.org/link/?jou/vol/firstpage, where "jou" is the three-letter journal abbreviation (e.g. jcp for Journal of Chemical Physics), "vol" is the volume number and "firstpage" the first page number. Example: http://link.aip.org/link/?jcp/115/2051 will link to J. Chem. Phys. 115, 2051 (2001).
10.1073 PNAS (Proceedings of the National Academy of Sciences [USA]). pnas.XXXXXXXXX, where XXXXXXXXX is a 9-digit manuscript number.
10.1074 Journal of Biological Chemistry. Structure: jbc.MXXXXXXXXX, where XXXXXXXXX is a 9-digit manuscript number.
10.1080 Taylor and Francis. This publisher uses 15-character PIIs like Elsevier; again, the PII can generally be found on the online abstract of the journal paper or on the first page of the printed paper. An example DOI URL is http://dx.doi.org/10.1080/002689799163172
10.1083 Rockefeller University Press (e.g. Journal of Cell Biology)
10.1092 Laser Pages Publishing (=Israel Journal of [fill in subject]). Structure: e.g. V0Q8-T3XM-N68W-D8NL.
10.1093 Oxford University Press, EMBO (European Molecular Biology Organisation). Structure: emboj/aaaXXX, where emboj stands for EMBO Journal and aaaXXX is a 3-letter, 3-digit article code.
10.1103 American Physical Society. Example: http://dx.doi.org/10.1103/PhysRevA.68.021801. As you see, JournalName.Volume.ArticleNumber. Like for AIP, an alternative URL is given as follows: http://link.aps.org/abstract/PRA/v68/e021801.
10.1107 International Union of Crystallography (e.g. Acta Crystallographica series). Uses PIIs in same way as Elsevier (see above).
10.1126 SCIENCE magazine. Structure: science.XXXXXXX, where XXXXXXX is a 7-digit article code.
10.1161 American Heart Association.
10.1182 American Society of hematology (e.g. the journal Bloo
