7722-71-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7722-71-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,2 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7722-71:
(6*7)+(5*7)+(4*2)+(3*2)+(2*7)+(1*1)=106
106 % 10 = 6
So 7722-71-6 is a valid CAS Registry Number.

The oxorhenium(VII)-catalyzed direct condensation of phosphoric acid with an alcohol
Sakakura, Akira,Katsukawa, Mikimoto,Ishihara, Kazuaki
, p. 1423 - 1426 (2008/03/15)
(Chemical Equation Presented) Come together ... over Re: Oxorhenium-(VII) complexes catalyze the direct condensation of phosphoric acid with an alcohol to selectively give the corresponding phosphoric acid monoester on a 2-100-mmol scale (see scheme). This method should be useful for the industrially important synthesis of phosphoric acid monoesters.
