JavaScript

var dt = new CkDateTime();

// A ULID must be exactly 26 chars in length,
// and is composed of the following chars: 0123456789ABCDEFGHJKMNPQRSTVWXYZ
// Note: The ULID alphabet excludes the letters I, L, O, and U

// Here's a valid ULID
var ulid = "01GRGCH4J88RECEN4D4VK4F629";
var valid = dt.UlidValidate(ulid);
console.log("valid: " + valid);

// Here's an invalid ULID
ulid = "71GRGxx4Jr8RECEN4D4VK4F62!";
valid = dt.UlidValidate(ulid);
console.log("valid: " + valid);
