16941-92-7 Usage
Uses
Hexachloro-iridate(2-) Dihydrogen is used as a catalyst for formic acid electro-oxidation
Flammability and Explosibility
Nonflammable
Purification Methods
If it contains nitrogen, then repeatedly concentrate a conc HCl solution until free from nitrogen, and dry free from HCl in a vacuum over CaO until crystals are formed. The olive-green solid (yellow at ~700o) is very hygroscopic. [Woo & Yost J Am Chem Soc 53 884 1931, Grube in Handbook of Preparative Inorganic Chemistry (Ed.

Check Digit Verification of cas no
The CAS Registry Mumber 16941-92-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,9,4 and 1 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 16941-92:
(7*1)+(6*6)+(5*9)+(4*4)+(3*1)+(2*9)+(1*2)=127
127 % 10 = 7
So 16941-92-7 is a valid CAS Registry Number.
