6664-99-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6664-99-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,6 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6664-99:
(6*6)+(5*6)+(4*6)+(3*4)+(2*9)+(1*9)=129
129 % 10 = 9
So 6664-99-9 is a valid CAS Registry Number.

SILYL NITRONATES AND NITRILE OXIDES IN ORGANIC SYNTHESIS. A NOVEL ROUTE TO D,L-DEOXYSUGARS. USE OF ALUMINIUM OXIDE AS SOLID PHASE BASE FOR GENERATION OF NITRILE OXIDES FROM HYDROXIMIC ACID CHLORIDES

Torssell, K. B. G.,Hazell, A. C.,Hazell, R. G.

, p. 5569 - 5576 (2007/10/02)

Novel methodology is developed for a three step synthesis of deoxyaldoses and deoxyketoses. 1.Regioselective addition of silyl nitronate or nitrile oxide to a diene. 2.Stereospecific hydroxylation of the double bond. 3.Unmasking of the aldol moiety by catalytic reduction of the 2-isoxazoline.The syntheses of D.L-deoxyribose, D,L-oleose, D,L-digitoxose, D,L-2-deoxygalactose, 1,3-dideoxyfructose, 3-deoxyfructose etc. are described.Basic aluminium oxide is introduced as a solid phase base for the one step synthesis of 2-isoxazolines from aldoximes and olefins.An X-ray diffraction study of compound 13c verifies the stereochemical assignments.
