/**
 * Estonian registry code (`registrikood`, Peppol `0191` / `EE:CC`) check — GPR-1396.
 *
 * Eight digits. The last is a check digit computed like the Estonian personal
 * identification code: weights 1..7 over the first seven digits, modulo 11; if
 * that gives 10, weights 3..9 instead; if THAT gives 10 too, the check digit is 0.
 *
 * The authority is the OpenPeppol participant identifier code list v9.7 (entry
 * `0191`, versioned in the console under `peppol-eas-codelist/`): `RegEx:
 * [1789][0-9]{7}`, "CheckDigit as last char", with exactly this two-pass
 * computation. The register agrees: every one of the 379 111 entities in the
 * Äriregister open data of 2026-10-03 passes it, and every one starts with 1, 7,
 * 8 or 9. A code it refuses is a code the register has never issued.
 *
 * No prefix is accepted: Storecove refuses `EE19900019` at registration
 * (`^\d{8}$`, measured 2026-10-03), and 999 of 1 000 live `0191` participants
 * sampled from the Peppol Directory carry none.
