Check Digit Verification of cas no

The CAS Registry Mumber 111099-08-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,0,9 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 111099-08:
(8*1)+(7*1)+(6*1)+(5*0)+(4*9)+(3*9)+(2*0)+(1*8)=92
92 % 10 = 2
So 111099-08-2 is a valid CAS Registry Number.

ALDOLISATION STEREOCONTROLEE PAR UN GROUPE TERMOLABILE. SYNTHESE STEREOSELECTIVE DE COMPOSES POSSEDANT TROIS CARBONES ASYMMETRIQUES CONSECUTIFS.

Bloch, R.,Gilbert, L.

, p. 2523 - 2540 (2007/10/02)

The bulkiness of thermolabile norbornenyl and oxanorbornenyl groups has been used to induce good to excellent syn diastereoselective aldol condensations between Diels-Alder adducts of α,β-ethylenic ketones and various aldehydes.The aldols thus obtained gi

STEREOSELECTIVE ALDOL CONDENSATIONS INDUCED BY A THERMOLABILE GROUP.

Bloch, R.,Gilbert, L.

, p. 3511 - 3514 (2007/10/02)

Diastereoselective aldol condensations between exo, endo and 2-methyl endo bicyclo-5-hepten-2-yl ethyl ketones and aldehydes are achieved via the ketones Z-lithium enolates prepared with lithium hexamethyldisilazide.The aldols thus obtained give rise by a retro Diels-Alder reaction to syn α-methyl-β-siloxy-α'-ethylenic ketones of potential value for polyhydroxylated natural product synthesis.
