Check Digit Verification of cas no

The CAS Registry Mumber 1241474-56-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,1,4,7 and 4 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1241474-56:
(9*1)+(8*2)+(7*4)+(6*1)+(5*4)+(4*7)+(3*4)+(2*5)+(1*6)=135
135 % 10 = 5
So 1241474-56-5 is a valid CAS Registry Number.

Structure of aldose condensation products with 2-hydroxyand 2-sulfanylbenzohydrazides

experimental part, p. 860 - 865 (2010/10/21)

The structure of the condensation products of 2-hydroxy- and 2-sulfanylbenzohydrazides with a series of aldoses (L-arabinose, D-ribose, L-ramnose, D-galactose, D-glucose, D-mannose) was studied by 1H and 13C NMR spectroscopy. The condensation products of monosaccharides with 2-hydroxybenzohydrazide in DMSO-d 6 solution exist as equilibrium mixtures of linear hydrazone and cyclic pyranose and furanose forms, the cyclic tautomers being represented by two stereoisomers (α- and β-anomers). The aldose condensation products with 2-sulfanylbenzohydrazide in the crystalline state have cyclic 1,3,4-benzothiadiazepine structure, while in DMSO-d 6 solution they undergo complete or partial isomerization into cyclic pyranose tautomer.
