Check Digit Verification of cas no

The CAS Registry Mumber 548786-21-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,8,7,8 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 548786-21:
(8*5)+(7*4)+(6*8)+(5*7)+(4*8)+(3*6)+(2*2)+(1*1)=206
206 % 10 = 6
So 548786-21-6 is a valid CAS Registry Number.

Triflimide activation of a chiral oxazaborolidine leads to a more general catalytic system for enantioselective Diels-Alder addition

Ryu, Do Hyun,Corey

, p. 6388 - 6390 (2003)

The strong acid triflimide ((CF3SO2)2NH) protonates chiral oxazaborolidines to form superactive, stable, chiral Lewis acids which are highly effective catalysts for a wide variety of enantioselective Diels-Alder reactions, documented herein by more than 20 examples. Copyright
