// Standard Luhn algorithm to generate check digit (last digit) for IMEI function computeLuhnCheckDigit(partial14) if (partial14.length !== 14) return partial14; // fallback let sum = 0; for (let i = 0; i < 14; i++) let digit = parseInt(partial14[i], 10); // positions from left: double every second digit from leftmost? IMEI uses Luhn: double digits in even positions (starting from rightmost? easier: typical) // Actually IMEI (14 base + check): starting from rightmost digit (excluding check), double every second digit. // For simplicity: Convert to array and apply Luhn from right. let posFromRight = 13 - i; // 0-based from right (last digit of 14) let val = digit; if (posFromRight % 2 === 1) // double every second digit from right (odd positions from right) val = digit * 2; if (val > 9) val = val - 9; // main calculation trigger function calculate()
