Check Digit Verification of cas no

The CAS Registry Mumber 420803-57-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,0,8,0 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 420803-57:
(8*4)+(7*2)+(6*0)+(5*8)+(4*0)+(3*3)+(2*5)+(1*7)=112
112 % 10 = 2
So 420803-57-2 is a valid CAS Registry Number.

Organocopper-mediated alkylation of β-(N-Boc-2-oxo-1,3-oxazolidin-5-yl)-α,β-enoates has been intensively investigated. Alkylation proceeded regio- and stereoselectively by anti-SN2′ ring-opening to provide a new route to the synthesis of Ψ[(E)-
