Query: Some mistakes make the book hard to believe

It may be that the book is a good work, but some mistakes make it hard to believe. As a simple but illustrative example, on page 315 the author says that some synonyms of carbon tetrachloride (formula CCl4) are "carbon disulphide, carbon disulfide" and some others that are not, in any way, related to carbon tetrachloride but to other chemical (formula CS2). If this so obvious mistake is found, how many others, not so obvious might be in the book?
