10002199

10002199 is the integer ten million, two thousand, one hundred ninety-nine. As a natural number it occupies the range of eight-digit base-10 numerals and is greater than 10,000,000 but less than 11,000,000. In basic arithmetic terms the number is odd, not divisible by 2 or 5, and its digit sum is 22, giving a digital root of 4; consequently it is not divisible by 3 or 9.

In mathematical contexts numbers of this magnitude are considered in studies of number theory, combinatorics, and computational tasks where size and digit patterns matter. The specific pattern of digits (1-0-0-0-2-1-9-9) is non-palindromic and contains repeated zeros and nines, features sometimes of interest in recreational mathematics or encoding schemes.

Beyond pure mathematics, eight-digit numbers like 10002199 commonly serve as identifiers in databases, catalogues, product serials, accession numbers, and other information systems. They can function as compact, human-readable primary keys in administrative and technical contexts. Because the sequence itself has no single, universally recognized referent, its meaning depends entirely on the system or dataset in which it is used. References to 10002199 in documentation should therefore clarify the domain and the assignment rules governing that identifier.
