When {{cs1}} and {{cs2}} templates contain {{para|asin}}, a test is done to see if the [[ASIN]] identifier contains ten upper-case alphanumeric characters without punctuation or spaces and that if the first character is numeric, that the ASIN conforms to the rules for a ten-digit [[ISBN]].  

To resolve this error, ensure that the {{para|asin}} value is correct.

If the {{para|asin}} value is correct and all-numeric, use {{para|isbn}} instead and delete any {{para|asin-tld}} parameters.
