Check Digit Verification of cas no
The CAS Registry Mumber 103447-97-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,4,4 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 103447-97:
(8*1)+(7*0)+(6*3)+(5*4)+(4*4)+(3*7)+(2*9)+(1*7)=108
108 % 10 = 8
So 103447-97-8 is a valid CAS Registry Number.

Enhanced reactivity of secondary hydroxyl groups in the O-alkylation of carbohydrate-related primary-secondary vic-glycols. Regioselective 2-O-benzylation of 1,3:2,4-di-O-ethylidene-D-glucitol

Partial O-alkylation of 1,3:2,4-di-O-ethylidene-D-glucitol (1a), 1,2-O-isopropylidene-3-O-methyl-α-D-glucofuranose (1b), and R-(+)-1-O-benzylglycerol (1c) with benzyl chloride in a KOH/DMSO system results in products of monoalkylation at the secondary (4a-c) and at the primary hydroxyl (2a-c) in ratios of over 95:5 (a), ca. 2:1 (b), and ca. 1:1 (c), whereas (+/-)propane-1,2-diol (1d) gives only the product of 1-O-benzylation (2d).A qualitatively similar result is observed upon O-alkylation of diols (1a-e) with 2-methoxyethanol tosylate.
