About Russian SNILS (Individual Insurance Account Number)
The SNILS (Страховой номер индивидуального лицевого счёта) is the personal social security and pension account number in Russia, administered by the Social Fund of Russia (SFR).
Composed of 11 digits formatted as 'XXX-XXX-XXX YY', where the first 9 digits form the account number and the last 2 digits constitute a Modulo 101 checksum.
Check Digit Calculation Algorithm (Modulo 101)
- Compute weighted sum: Sum = Σ(d[i] × (9 - i)) across the first 9 positions.
- If Sum < 100, check digit is Sum.
- If Sum is 100 or 101, check digit is 00.
- If Sum > 101, compute Remainder = Sum % 101. If Remainder is 100 or 101, CD is 00; otherwise CD equals Remainder.
