Check Digit Verification of cas no

The CAS Registry Mumber 58769-78-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,7,6 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 58769-78:
(7*5)+(6*8)+(5*7)+(4*6)+(3*9)+(2*7)+(1*8)=191
191 % 10 = 1
So 58769-78-1 is a valid CAS Registry Number.

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.

THE SYNTHESIS OF 3-ACETAMIDO-2,3,5,6-TETRADEOXY-5-FLUORO-D,L-ribo-HEXOFURANOSE BY THE DIRECT FLUORINATION OF METHYL 3-ACETAMIDO-2,3,6-TRIDEOXY-D,L-arabino-HEXOPYRANOSIDE (METHYL N-ACETYL-D,L-ACOSAMINIDE)

Welch, John T.,Svahn, Britt-Marie,Eswarakrishnan, Seetha,Hutchinson, John P.,Zubieta, Jon

, p. 221 - 232 (2007/10/02)

3-Acetamido-2,3,5,6-tetradeoxy-5-fluoro-D,L-ribo-hexofuranose was synthesized by direct, fluorinative dehydroxylation of methyl 3-acetamido-2,3,6-trideoxy-D,L-arabino-hexopyranoside with sulfur tetrafluoride-hydrogen fluoride.The furanose form and the ribo configuration, indicated by 13C- and 1H-n. m. r. spectroscopy, respectively, were confirmed by a single-crystal, X-ray diffraction study.
