51842-38-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 51842-38-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,8,4 and 2 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 51842-38:
(7*5)+(6*1)+(5*8)+(4*4)+(3*2)+(2*3)+(1*8)=117
117 % 10 = 7
So 51842-38-7 is a valid CAS Registry Number.

A reversal in the order of H-6R and H-6S chemical shifts of some aldohexopyranose derivatives, associated with the acetylation of OH-4 and OH-6 groups. A distinction between 3- and 4-linked D-glucose residues in disaccharides

Rao, Vanga S.,Perlin, Arthur S.

, p. 2688 - 2694 (2007/10/02)

On peracetylation of methyl α- or β-D-glucopyranose, there is a reversal in the order of the chemical shifts of the 6,6'-methylene protons, i.e., whereas the H-6S signal appears downfield of H-6R in the spectra of the glucosides, the
