General Description
Metatartaric acid, also known as pyrotartaric acid, is a chemical compound that is derived from tartaric acid. It is a white crystalline solid that is soluble in water. Metatartaric acid is commonly used as a stabilizing agent in the wine industry to prevent the formation of tartrate crystals in bottled wines. It works by binding to potassium and calcium ions, preventing them from combining with tartaric acid and forming crystals. This helps to improve the clarity and stability of the wine. Additionally, metatartaric acid is used as a chelating agent in various industrial processes and as a food additive to improve the stability and appearance of certain products.Check Digit Verification of cas no
The CAS Registry Mumber 39469-81-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,4,6 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.Calculate Digit Verification of CAS Registry Number 39469-81:
(7*3)+(6*9)+(5*4)+(4*6)+(3*9)+(2*8)+(1*1)=163
163 % 10 = 3
So 39469-81-3 is a valid CAS Registry Number.
