Propanoic acid, 3,3'-oxybis-, disodium salt, also known as disodium 3,3'-oxybispropanoate or disodium malonate, is a chemical compound with the formula C6H8Na2O5. It is a white crystalline solid that is soluble in water and slightly soluble in ethanol. Propanoic acid, 3,3'-oxybis-, disodium salt is formed by the reaction of propanoic acid with sodium hydroxide, resulting in the formation of a disodium salt. It is commonly used as a chelating agent, sequestrant, and buffer in various industrial applications, including water treatment, detergents, and food processing. Additionally, it serves as a precursor in the synthesis of other chemicals and pharmaceuticals. Due to its ability to bind with metal ions, it is also employed in the removal of heavy metals from wastewater.

821-34-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 821-34-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,2 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 821-34:
(5*8)+(4*2)+(3*1)+(2*3)+(1*4)=61
61 % 10 = 1
So 821-34-1 is a valid CAS Registry Number.
