International codes in the identification of chemicals

International Chemical Codes are used to identify chemicals from each other, these chemical codes are used to identify hazards in the transport or use of chemicals. International chemical codes only express the chemical inside the party and do not determine the manufacturer.

UN number

The UN Number is a four-digit numerical coding system established internationally to identify dangerous goods. These numbers range from UN0001 to UN3500 and are specified by the United Nations Special Committee on the Transport of Dangerous Goods. In this system, a UN number may be specific to a substance (such as phenol with UN1671). Sometimes a number may belong to a group of substances with similar hazards. In some cases, if a substance in solid and liquid states has different properties, it may have different numbers.

Number NA

The NA number belongs to North America and is also known as the DOT number due to the fact that it is issued by the US Department of Transportation. This coding system is similar to the UN numerical system, except that some materials that do not have a UN number may have an NA number. These additional numbers include NA8000 to NA9999.

CAS registration number

The CAS Registry Number is a numeric coding system in the xxx-xx-x format that is designed to identify various chemical elements and compounds (such as benzene with 2-43-71.CAS No). This system is serviced by the Chemical Abstracts Service. Chemical, which is a branch of the American Chemical Society. Since a material may have synonymous and different names, the purpose of this system is to facilitate the identification and search of material information so that most information systems allow the search through this registration system.

IUPAC number

IUPAC or IUPAC is an international coding system for the identification of chemicals and is designed to provide a standard and understandable method for identifying molecular information of materials and facilitating the search for this information. The IOPAC system was developed by the International Union of Pure and Applied Chemistry.

RTECS number

Number RTECS or Number RTECS is a system for recording toxic effects of chemical substances (Registry of Toxic Effects of Chemical Substances) in ABxxxxxxx format. (Like benzene with CY1400000 #: RTECS). This material information and registration system, developed by NIOSH using existing toxicology studies, helps to obtain toxicological information about a chemical.
