Check Digit Verification of cas no

The CAS Registry Mumber 676168-79-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,6,1,6 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 676168-79:
(8*6)+(7*7)+(6*6)+(5*1)+(4*6)+(3*8)+(2*7)+(1*9)=209
209 % 10 = 9
So 676168-79-9 is a valid CAS Registry Number.

A convenient route to 1-(2-oxiranyl)-1,4-diketones and their application to the synthesis of endo-brevicomin, endo-isobrevicomin, frontalin and related compounds via alkylated 6,8-dioxabicyclo[3.2.1]octan-2-ones

Tyvorskii, Vladimir I.,Astashko, Dmitry A.,Kulinkovich, Oleg G.

, p. 1473 - 1479 (2007/10/03)

1-(2-Oxiranyl)-1,4-alkanediones were prepared from the ethylene acetals of ethyl 4-oxoalkanoates via the oxidation of the intermediate 1,2- dialkylcyclopropanols having a protected carbonyl group in an aliphatic chain. Intramolecular acetalization of these epoxy dicarbonyl compounds gave alkylated 6,8-dioxabicyclo[3.2.1]octan-2-ones in good yields. The latter were found suitable to be precursors for (±)-endo-brevicomin and its 2-hydroxy derivative, as well as (±)-endo-isobrevicomin and (±)-frontalin.
