Check Digit Verification of cas no
The CAS Registry Mumber 722-56-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,2 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 722-56:
(5*7)+(4*2)+(3*2)+(2*5)+(1*6)=65
65 % 10 = 5
So 722-56-5 is a valid CAS Registry Number.

Oxidative Anion Metatheses in Diaryliodonium Iodides and Chlorides
Kazmierczak, Pawel,Skulski, Lech
, p. 219 - 224 (2007/10/03)
Oxidative anion metatheses in the crude title iodides and chlorides produced the corresponding pure hydrogensulfates, nitrates, tetrafluoroborates, triflates, tosylates, as well as bromides and chlorides (only from the iodides) in 54-86% yields. These procedures are easier and shorter than earlier methods. By using modified oxidative metatheses in the title iodides (in the presence of HBr or HCl) it was possible either to isolate, or to detect only, the intermediate dihaloiodates(I). [Ar2I]+[IX2]- (X = Br or Cl). A complex Ph2I+Cl- -1/2I2 was also obtained in 56% yield. Tetraethylammonium iodide was similarly converted into pure tetrafluoroborate or dibromoiodate(I) in 75 and 76% yields, respectively.
