57690-62-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 57690-62-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,6,9 and 0 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 57690-62:
(7*5)+(6*7)+(5*6)+(4*9)+(3*0)+(2*6)+(1*2)=157
157 % 10 = 7
So 57690-62-7 is a valid CAS Registry Number.

Improved and large-scale synthesis of different protected d-glucuronals

Mikula, Hannes,Matscheko, Dominik,Schwarz, Markus,Hametner, Christian,Fr?hlich, Johannes

, p. 19 - 23 (2013/04/23)

Although different protected d-glucuronals are used as precursors for the preparation of many compounds, standard procedures and large-scale syntheses are still not described in the literature. In the course of the development of different protected d-glucuronyl donors we developed several versatile methods that can be used for fast and reproducible preparation of large amounts of the key intermediates. d-Glucuronolactone was converted to methyl 3,4-di-O-acetyl-d-glucuronal applying a novel one-pot protocol, which allowed for large-scale synthesis. Introduction of silyl and benzyl groups was achieved using optimized procedures. Furthermore 3,4,6-tri-O-acetyl-d-glucal was used as starting material for an improved preparation of benzyl protected d-glucuronal, which significantly accelerates and simplifies similar methods described in the literature.

X-ray diffraction and high-resolution NMR spectroscopy of methyl 3,4-di-O-acetyl-1,5-anhydro-2-deoxy-d-arabino-hex-1-enopyranuronate

Liberek, Beata,Tuwalska, Dorota,Konitz, Antoni,Sikorski, Artur

, p. 1280 - 1284 (2008/02/02)

Single-crystal X-ray diffraction and high-resolution 1H and 13C NMR spectral data for methyl 3,4-di-O-acetyl-1,5-anhydro-2-deoxy-d-arabino-hex-1-enopyranuronate are reported. The 5H4 conformation was found to be the preferred form for this glycal, both in the crystal lattice and in solution. The factors determining the 4H5 ? 5H4 conformational equilibrium for acetylated glycals are discussed.
