var checksumSeed = 5 // required
var checksumIdx = 7 // optional (default Math.floor(code length / 2))

var code = ticketCode.generate(checksumSeed, codeLength, checksumIdx)  // NPP3YHPEQMCY75W
// ...

ticketCode.validate('NPP3YHPEQMCY75W', checksumSeed, checksumIdx)  // true
ticketCode.validate('NPP3YHPEQMCY75A', checksumSeed, checksumIdx)  // false
