Check Digit Verification of cas no

The CAS Registry Mumber 256510-27-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,6,5,1 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 256510-27:
(8*2)+(7*5)+(6*6)+(5*5)+(4*1)+(3*0)+(2*2)+(1*7)=127
127 % 10 = 7
So 256510-27-7 is a valid CAS Registry Number.

Diastereoselective 1,3-dipolar cycloaddition of nitrilimines to γ-oxygenated α,β-unsaturated enones and esters

Grubert, Lutz,Galley, Guido,Paetzel, Michael

, p. 1137 - 1148 (1996)

The stereochemical outcome of the 1,3-dipolar cycloaddition of nitrilimines to γ-oxygenated α,β-unsaturated enones and esters was investigated. By means of X-ray and NMR analysis the main diastereomers were assigned as the syn-derivatives. Novel enantiomerically pure nitrilimines were included in the investigations but did not influence the stereochemical course of the cycloaddition significantly.
