Check Digit Verification of cas no

The CAS Registry Mumber 1301601-27-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,1,6,0 and 1 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1301601-27:
(9*1)+(8*3)+(7*0)+(6*1)+(5*6)+(4*0)+(3*1)+(2*2)+(1*7)=83
83 % 10 = 3
So 1301601-27-3 is a valid CAS Registry Number.

Steering reaction pathways: From benzyl Claisen rearrangements to powerful ionic shifts

Valerio, Viviana,Madelaine, Claire,Maulide, Nuno

, p. 4742 - 4745 (2011/05/19)

Take a walk on the wild side: A novel benzyl Claisen cascade rearrangement of keteniminium salts is described. The reaction leads to α-arylated lactones under metal-free conditions (top scheme; Tf=trifluoromethanesulfonyl). It is further demonstrated that the cationic intermediates involved can be steered away from pericyclic reaction manifolds into powerful ionic shifts through reaction design (bottom scheme).
