No, a 13-digit ISBN uses modulo 10 in calculation of the check digit, so the check digit can be only 0 to 9. Other digits are also 0 to 9 in any versions of ISBN. See this Wikipedia article for details.
The calculation of an ISBN-13 check digit begins with the first 12 digits of the thirteen-digit ISBN (thus excluding the check digit itself). Each digit, from left to right, is alternately multiplied by 1 or 3, then those products are summed modulo 10 to give a value ranging from 0 to 9. Subtracted from 10, that leaves a result from 1 to 10. A zero (0) replaces a ten (10), so, in all cases, a single check digit results.

不,10 位 ISBN 可以...请参阅 http://en.wikipedia .org/wiki/International_Standard_Book_Number#ISBN-13
No, a 10-digit ISBN can, though... See http://en.wikipedia.org/wiki/International_Standard_Book_Number#ISBN-13
不可以,13位ISBN在计算校验位时使用模10,因此校验位只能是0到9。在任何版本的ISBN中,其他数字也是0到9。有关详细信息,请参阅这篇维基百科文章。
