Check Digit Verification of cas no

The CAS Registry Mumber 1221896-03-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,8,9 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1221896-03:
(9*1)+(8*2)+(7*2)+(6*1)+(5*8)+(4*9)+(3*6)+(2*0)+(1*3)=142
142 % 10 = 2
So 1221896-03-2 is a valid CAS Registry Number.

Unexpected electrophilic rearrangements of amides: A stereoselective entry to challenging substituted lactones

Madelaine, Claire,Valerio, Viviana,Maulide, Nuno

supporting information; experimental part, p. 1583 - 1586 (2010/06/15)

"Chemical Equation Presented" Surprise, surprise! An unexpected skeletal rearrangement was developed into a chemo- and stereoselective synthesis of aallyl and allenyl lactones with challenging substitution patterns (see scheme; EWC = electron-withdrawing group). The generality, unique features, and synthetic potential of this reaction were probed and a mechanism was proposed.
