82742-24-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 82742-24-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,7,4 and 2 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 82742-24:
(7*8)+(6*2)+(5*7)+(4*4)+(3*2)+(2*2)+(1*4)=133
133 % 10 = 3
So 82742-24-3 is a valid CAS Registry Number.

Synthethic Routes to 3-C-Cyano-3-deoxy-D-galactopyranose Derivatives

Mubarak, Azeez,Fraser-Reid, Bert

, p. 4265 - 4268 (1982)

Routes to 3-C-cyano-3-deoxy-D-galactopyranose derivatives have been developed from methyl 3,4-anhydro-α-D-galactopyranoside and 1,6:3,4-dianhydro-β-D-galactopyranose.Upon treatment with diethylaluminum cyanide, both precursors give products of trans-diaxial opening although some diequatorial opening also occurs with the former.The axial C-cyano groups in both cases are readily epimerized by dilute sodium methoxide, giving 3-C-cyano-3-deoxy-D-galacto products.In neither case is there any evidence of β elimination or of skeletal rearrangements.
