Check Digit Verification of cas no

The CAS Registry Mumber 1357059-20-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,7,0,5 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1357059-20:
(9*1)+(8*3)+(7*5)+(6*7)+(5*0)+(4*5)+(3*9)+(2*2)+(1*0)=161
161 % 10 = 1
So 1357059-20-1 is a valid CAS Registry Number.

Si-free enolate Claisen rearrangements of enamido substrates

Harker, Wesley R. R.,Carswell, Emma L.,Carbery, David R.

supporting information; experimental part, p. 1406 - 1410 (2012/04/05)

α-Alkyl β-amino esters are available in high diastereoselectivity through a silicon-free Claisen enolate [3,3]-sigmatropic rearrangement of enamide esters. Optimisation studies have probed the crucial role of the initial enolisation and the nature of the enamide N-centre. The demonstration of chirality transfer and the formation of β-proline systems, is also presented.
