# 读入
isbn = list(input())
# '-'的下标位置列表
lst = [1,5,11]
# 校验和初始化
checksum = 0
# 倒着读lst，防止删除元素后导致下标变化
for i in lst[::-1]:
    del isbn[i]
# 计算校验和
for i in range(len(isbn)-1):
    checksum += int(isbn[i]) * (i + 1)
checksum %= 11
last = str(checksum)
# 求余为10则变为'X'
if last == '10':
    last = 'X'
# 校验和检测
if last == isbn[-1]:
