The publisher assigns a DOI when your article is published and made available electronically. All DOI numbers begin with a 10 and contain a prefix and a suffix separated by a slash. The prefix is a unique number of four or more digits assigned to organizations; the suffix is assigned by the publisher and was designed to be flexible with publisher identification standards...The DOI is typically located on the first page of the electronic journal article, near the copyright notice (see Figure 6.2). The DOI can also be found on the database landing page for the article (see Figure 6.3)
Are you looking at specific articles from Standard & Poor and Statista? What company website? Typically a company website would not have a DOI.
