6605-26-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6605-26-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,0 and 5 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6605-26:
(6*6)+(5*6)+(4*0)+(3*5)+(2*2)+(1*6)=91
91 % 10 = 1
So 6605-26-1 is a valid CAS Registry Number.

The total synthesis of L-daunosamine

Jurczak, Janusz,Kozak, Janusz,Golebiowski, Adam

, p. 4231 - 4238 (2007/10/02)

N,O-Dibenzyl-N-tert-butoxycarbonyl-L-homoserinal (7), obtained from L-aspartic acid, reacts with vinylmagnesium chloride to afford with high stereoselectivity compound 6 which is subsequently transformed into the derivative of L

SYNTHESIS OF (L)-DAUNOSAMINE AND RELATED AMINO SUGARS

Sammes, Peter G.,Thetford, Dean

, p. 111 - 124 (2007/10/02)

1-(2-Furyl)ethanol (6) has been converted into methyl (+/-)-daunosaminide (1) and methyl (+/-)-ristosaminide (3) by use of an intramolecular cyclisation of a trichloroacetimidate group. (+/-)-Daunosamine (1) has been obtained more directly from the alcohol (10) by use of a modified Mitsunobu reaction; the scope of the latter reaction has been explored using cyclohex-2-en-1-ol as a model substrate.Asymmetric reduction of 2-acetylfuran (5) has given (S)-1-(2-furyl)ethanol (46) in good enantiomeric excess, thus providing a short route to the L-enantiomers of the amino sugars (1), (2), and (3) from a cheap, non-carbohydrate precursor.
