188923-21-9 Usage

General Description

AOA acetate, also known as acetamidoxime acetate, is a chemical compound used in the extraction and separation of precious metals such as gold, silver, and platinum from ores and waste materials. It is a powerful chelating agent that forms stable complexes with metal ions, allowing for efficient and selective recovery of valuable metals from complex mixtures. AOA acetate is also used in the development of new technologies for the recycling of electronic waste and other industrial by-products, providing a sustainable and environmentally friendly solution for metal recovery. Its use in metal extraction and recycling processes has made AOA acetate an important chemical in the field of resource recovery and environmental sustainability.

Check Digit Verification of cas no

The CAS Registry Mumber 188923-21-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,9,2 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 188923-21:
(8*1)+(7*8)+(6*8)+(5*9)+(4*2)+(3*3)+(2*2)+(1*1)=179
179 % 10 = 9
So 188923-21-9 is a valid CAS Registry Number.
