ISBN-$10$
The ISBN-$10$ format consists of a string of $9$ digits followed by a check digit in the set $\set {0, 1, \ldots, 9, X}$.
The check digit $d$ is calculated as follows.
Let $c$ be calculated as:
- $c = \ds \sum_{k \mathop = 1}^9 k d_k \pmod {11}$
where $d_k$ denotes the $k$th digit in the ISBN-$10$.
Then the check digit $d$ is defined as:
- $d = \begin {cases} c & : c \le 9 \\ X &: c = 10 \end {cases}$
ISBN-$13$
The ISBN-$13$ format consists of a string of $12$ digits followed by a check digit.
The check digit $d$ is calculated as:
- $d = \ds \sum_{k \mathop = 1}^{12} k d_k \pmod {10}$
