Check Digit Verification of cas no
The CAS Registry Mumber 20816-78-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,1 and 6 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 20816-78:
(7*2)+(6*0)+(5*8)+(4*1)+(3*6)+(2*7)+(1*8)=98
98 % 10 = 8
So 20816-78-8 is a valid CAS Registry Number.

Photoexcited proton transfer from enhanced photoacids
Tolbert, Laren M.,Haubrich, Jeanne E.
, p. 10593 - 10600 (2007/10/02)
Naphthols with electron-withdrawing groups such as cyano or methanesulfonyl at C-5 and C-8 exhibit greatly enhanced photoacidity. This increase in photoacidity enables the substituted naphthols to undergo excited-state proton transfer (ESPT) in alcohols and Me2SO in the absence of water. In aqueous tetrahydrofuran solution, efficient proton transfer to water occurs at much lower water concentrations than with the parent naphthol, and the kinetics of proton transfer indicate that a smaller water cluster is involved.
