CorelDRAW seems to have the option to specially export its documents / drawings for Microsoft Office programs including Microsoft Word, which is more or less how you can most conveniently convert cdr to doc.
You can achieve cdr to doc conversion or export with the File ► Export for Office... function. With this function you can send your CorelDRAW data directly to Microsoft Word, where it can be used and saved as a document (.doc, .docx). This is mostly likely the easiest way for cdr to doc export, but requires both programs to be installed on your computer at the same time.
You may also try printing your CorelDRAW document to a PDF format and importing it to MS Word 2013 or later.
