Check Digit Verification of cas no

The CAS Registry Mumber 21067-47-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,0,6 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 21067-47:
(7*2)+(6*1)+(5*0)+(4*6)+(3*7)+(2*4)+(1*7)=80
80 % 10 = 0
So 21067-47-0 is a valid CAS Registry Number.

Copper-catalyzed rearrangement of N-aryl nitrones into epoxyketimines

Mo, Dong-Liang,Anderson, Laura L.

, p. 6722 - 6725 (2013)

Please pass the oxygen: A new method for the preparation of trans-α,β-epoxyketimines has been achieved through a copper-catalyzed rearrangement of (E)-α,β-unsaturated nitrones. The scope and tolerance of the method is evaluated and the synthetic utility of the products is demonstrated. The new transformation provides facile access to an unusual, densely functionalized intermediate that can be exploited for further synthetic application. Copyright
