CAS' decision means Chernova also loses her London 2012 bronze medal, with Lithuania's Austra Skujyte upgraded from fourth place.
CAS also confirmed Chernova would be 'sanctioned with a period of ineligibility of three years and eight months, beginning on 5 February, 2016.'Also included in Tuesday's statement were details of sanctions for Russian track duo Ekaterina Sharmina and Kristina Ugarova after blood doping was identified following analysis of their athlete biological passports.
She rebounded the following year at the 2008 IAAF World Indoor Championships, where she came seventh in the women's pentathlon.
But Press Association Sport understands there will be several medal ceremonies - including one for veteran British distance runner Jo Pavey, who has been upgraded to bronze at the 2007 Worlds - during the 10-day championships, and not just for British athletes.
It is unlikely, however, that every British athlete currently owed a medal because of a rival's doping conviction will get a medal ceremony in London, as the cases from the 20 Olympics are taking longer to process.
London is staging the 16th IAAF World Athletics Championships from August 4-13.
Jessica Ennis-Hill is set to be awarded the World Championship gold medal from 2011 after the winner, Russian Tatyana Chernova, had her results annulled for doping.
Chernova beat Ennis-Hill to the heptathlon gold medal in Daegu on August 30, 2011, less than 12 months before the Briton became Olympic champion in London.
