Check Digit Verification of cas no

The CAS Registry Mumber 127104-25-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,1,0 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 127104-25:
(8*1)+(7*2)+(6*7)+(5*1)+(4*0)+(3*4)+(2*2)+(1*5)=90
90 % 10 = 0
So 127104-25-0 is a valid CAS Registry Number.

On the origins of diastereoselectivity in the alkylation of enolates derived from N-1-(1′-Naphthyl)ethyl-O-tert-butylhydroxamates: Chiral Weinreb amide equivalents

Davies, Stephen G.,Goodwin, Christopher J.,Hepworth, David,Roberts, Paul M.,Thomson, James E.

supporting information; experimental part, p. 1214 - 1227 (2010/04/26)

(Chemical Equation Presented) The stereochemical outcome observed upon alkylation of enolates derived from N-1-(1′-naphthyl)ethyl-O-tert- butylhydroxamates (chiral Weinreb amide equivalents) may be rationalized by a chiral relay mechanism. Deprotonation withKHMDS leads to a nonchelated (Z)-enolate inwhich the oxygen atoms adopt an anti-periplanar conformation. The configuration of the N-1-(1′-naphthyl)ethyl group dictates the conformation of the O-tert-butyl group and the configuration adopted by the adjacent pyramidal nitrogen atom. Highly diastereoselective enolate alkylation then proceeds anti to both the bulky tert-butyl group (sterically driven) and the N-lone pair (stereoelectronically driven).
