Tangential. A long time ago at a company far far away, this is how we did UUIDs that made up a TenantId and a UserId, using this exact same logic, minus the arithmetic. Great stuff.
(We wanted something UUID like but deterministic that we could easily decompose and do RBAC with, this was prior to the invention of JWT’s, OAuth, and scopes, worked at the time).
