For substituted substituents, the multiplying prefixes bis-, tris-, and tetrakis- are used higher multiplying prefixes are formed by replacing the "-ne" of the corresponding alkane with "-kis-". For simple substituents, i.e., when not themselves substituted, the multiplying prefixes di-, tri-, and tetra-, are generally used higher multiplying prefixes are formed by suppressing the ending "-ne" of the name of the corresponding alkane. The number of identical substituents to a parent compound is expressed according to Rule A-2.5 ( ref. Until recently, numerical terms higher than 199 have not been required but now, in order to avoid confusion from alternative suggestions, it seems advisable to give a clear method for extending the list. 1a) uses numerical terms to name saturated unbranched acyclic hydrocarbons containing up to 199 carbon atoms. This document provides the necessary guidance, based on principles already established, for generating numerical terms up to 9999 by using the infixes "cta" (for the hundreds digits) and "lia" (for the thousands digits) in a way quite analogous to the use of "conta" for the tens digits beyond twenty. Recently a desire has been expressed for numerical terms higher than 199. The use of these numerical terms for expressing identical substituents to a parent structure, and their modifications for use with "complex" substituents, is described in Rule A-2.5. Rule A-1.1 of the IUPAC Organic Nomenclature Rules illustrates the numerical terms through 199 in the names of saturated unbranched acyclic hydrocarbons. Numerical terms are used in chemical names for indicating a number of identical structural units in a compound.
