Ammonium bis(cyano-C)aurate, also known as ammonium gold(I) cyanide, is a chemical compound with the formula [Au(CN)2]-. It is a gold complex that contains gold in the +1 oxidation state, coordinated to two cyanide ligands. ammonium bis(cyano-C)aurate is of interest in the field of precious metal recovery and extraction, particularly in the cyanidation process used in gold mining. The cyanide ligands in this complex are strong σ-donors and π-acceptors, which contribute to the stability of the complex. Ammonium bis(cyano-C)aurate is a key intermediate in the extraction of gold from its ores, and its formation and subsequent reactions are crucial for the efficient recovery of gold.

Check Digit Verification of cas no

The CAS Registry Mumber 31096-40-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,0,9 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 31096-40:
(7*3)+(6*1)+(5*0)+(4*9)+(3*6)+(2*4)+(1*0)=89
89 % 10 = 9
So 31096-40-9 is a valid CAS Registry Number.
