Check Digit Verification of cas no

The CAS Registry Mumber 91798-48-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,7,9 and 8 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 91798-48:
(7*9)+(6*1)+(5*7)+(4*9)+(3*8)+(2*4)+(1*8)=180
180 % 10 = 0
So 91798-48-0 is a valid CAS Registry Number.

Benzoyl Trifluoromethanesulfonate. A Mild Reagent for the Benzoylation of Sterically Hindered Hydroxyls

Brown, Lindsey,Koreeda, Masato

, p. 3875 - 3880 (2007/10/02)

Benzoyl trifluoromethanesulfonate (BzOTf) is a highly efficient reagent for the benzoylation of a variety of alcohols under mild conditions.These include hindered secondary and tertiary hydroxyls, phenols, and α-glycols.Sensitive functionality is stable when the reaction is performed in the presence of pyridine.Several unique rearrangements of Lewis acidsensitive compounds were also effected.
