Check Digit Verification of cas no
The CAS Registry Mumber 3658-77-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,5 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3658-77:
(6*3)+(5*6)+(4*5)+(3*8)+(2*7)+(1*7)=113
113 % 10 = 3
So 3658-77-3 is a valid CAS Registry Number.

Comparison of 2-acetylfuran formation between ribose and glucose in the Maillard reaction
Wang, Yu,Ho, Chi-Tang
body text, p. 11997 - 12001 (2010/03/25)
Sugar type is a major factor regulating the reaction rates and pathways in Maillard reaction. Ribose and glucose were used to compare their reactivities and pathways of 2-acetylfuran formation. A stable isotope labeling method was used to study their reactivity. A 1:1 mixture of [13C 6]glucose and unlabeled ribose (or other unlabeled sugar) was reacted with proline at 145 °C for 40 min. The reactivity of each sugar was revealed by the ratio of isotopomers. The reactivity of sugars in 2-acetylfuran formation decreased in the order ribose, fructose, glucose, rhamnose, and sucrose. This method simplified the reaction system and the calculation process and gave a direct comparison of reactivity as seen via mass spectrum. The difference between glucose and ribose in 2-acetylfuran formation was that glucose could form 2-acetylfuran directly from cyclization of its intact carbon skeleton, whereas ribose first underwent degradation into fragments before forming a six-carbon unit leading to 2-acetylfuran. In the presence of cysteine, ribose could not generate 2-acetylfuran at a detectable level. When ribose was reacted with glycine, formaldehyde generated from glycine combined with ribose to form 2-acetylfuran. In other amino acids, a symmetric structure of the ribose intermediate was formed, making fragmentation more complicated.
Potential of gas chromatography-orthogonal acceleration time-of-flight mass spectrometry (GC-oaTOFMS) in flavor research

Gas chromatography-orthogonal acceleration time-of-flight mass spectrometry (GC-oaTOFMS) is an emerging technique offering a straightforward access to a resolving power up to 7000. This paper deals with the use of GC-oaTOFMS to identify the flavor components of a complex seafood flavor extract and to quantify furanones formed in model Maillard reactions. A seafood extract was selected as a representative example for complex food flavors and was previously analyzed using GC-quadrupole MS, leaving several molecules unidentified. GC-oaTOFMS analysis was focused on these unknowns to evaluate its potential in flavor research, particularly for determining exact masses, N-Methyldithiodimethylamine, 6-methyl-5-hepten-2-one, and tetrahydro-2,4-dimethyl-4H-pyrrolo- [2,1-d]-1,3,5-dithiazine were successfully identified on the basis of the precise mass determination of their molecular ions and their major fragments. A second set of experiments was performed to test the capabilities of the GC-oaTOFMS for quantification. Calibration curves were found to be linear over a dynamic range of 103 for the quantification of furanones. The quantitative data obtained using GC-oaTOFMS confirmed earlier results that the formation of 4-hydroxy-2,5-dimethyl-3(2H)-furanone was favored in the xylose/glycine model reaction and 2(or 5) -ethyl-4-hydroxy-5(or2)-methyl-3(2H)-furanone in the xylose/alanine model reaction. It was concluded that GC-oaTOFMS may become a powerful analytical tool for the flavor chemist for both identification and quantification purposes, the latter in particular when combined with stable isotope dilution assay.
Formation of Hydroxyfuranone and Hydroxypyranone Derivatives with DNA-Breaking Activity in the Maillard Reaction of Glucose and Albumin under Physiological Conditions

, p. 101 - 104 (2007/10/03)
Formation of DNA breaking hydroxyfuranone and hydroxypyranone derivatives in the Maillard reaction of glucose and bovine serum albumin (BSA) under physiological conditions was investigated. A mixture of glucose and BSA was incubated at 37 deg C in water or in 1 M phosphate buffer (pH 7.4). The ethyl acetate/2-propanol extract of the reaction mixtures showed significant DNA breaking activity against supercoiled DNA especially in the presence of Fe(III) ion. Gas chromatography/mass spectrometry analysis of the mixture revelaed the formation of DNA breaking hydroxyfuranones (HMF and DMHF) and hydroxypyranone (DDMP).
