Check Digit Verification of cas no

The CAS Registry Mumber 129395-88-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,3,9 and 5 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 129395-88:
(8*1)+(7*2)+(6*9)+(5*3)+(4*9)+(3*5)+(2*8)+(1*8)=166
166 % 10 = 6
So 129395-88-6 is a valid CAS Registry Number.

SYNTHESIS OF FLUORINE-CONTAINING NATURAL GASTRODIN AND ITS ANALOGUES

Lin, Yong-Da,Liang, Yu-Da,Liang, Shi-Gin,Zhang, Shi-Xiang,Chi, Ching-Sung

, p. 367 - 374 (2007/10/02)

Reactions of 2,3,4,6-tetra-O-acetyl-α-D-glucopyranosyl bromide (2) with p-hydroxybenzaldehyde, trifluoromethyl and fluoro substituted aniline and 2-amino-6-fluorobenzoic acid gave 1-O-(p-formylphenyl)-2,3,4,6-tetra-O-acetyl-β-D-glucopyranoside (3), 1-N-(m-trifluoromethylphenylamino)-2,3,4,6-tetra-O-acetyl-β-D-glucopyranoside (4a), 1-N-(2-carboxyl-3-fluorophenyl)-2,3,4,6-tetra-O-acetyl-β-D-glucopyranoside (4b) and 1-N-(p-fluorophenyl)-N-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranoside (4c) respectively. 1-O-(perfluoro-2-propoxypropionyl)-O-benzyl-2,3,4,6-tetra-O-acetyl-β-D-glucopyranoside (7) and 1-O-(m-trifluoromethylphenylaminobenzylidene)-2,3,4,6-tetra-O-acetyl-β-D-glucopyranoside (8) were also prepared in subsequent reactions.Conversion of the acetyl group to the hydroxyl group yielded the corresponding deprotected product.The compounds formed have been characterized by analysis, IR, 1H and 19F NMR and mass spectroscopy.The influence of phase-transfer catalysts on the reactions is discussed.
