Check Digit Verification of cas no

The CAS Registry Mumber 59022-78-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,0,2 and 2 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 59022-78:
(7*5)+(6*9)+(5*0)+(4*2)+(3*2)+(2*7)+(1*8)=125
125 % 10 = 5
So 59022-78-5 is a valid CAS Registry Number.

5-Substituted imidazole-4-acetic acid analogues: Synthesis, modeling, and pharmacological characterization of a series of novel γ-aminobutyric acidC receptor agonists

Madsen, Christian,Jensen, Anders A.,Liljefors, Tommy,Kristiansen, Uffe,Nielsen, Birgitte,Hansen, Camilla P.,Larsen, Mogens,Ebert, Bjarke,Bang-Andersen, Benny,Krogsgaard-Larsen, Povl,Fr?lund, Bente

, p. 4147 - 4161 (2008/02/13)

A series of ring-substituted analogues of imidazole-4-acetic acid (IAA, 4), a partial agonist at both GABAA and GABAC receptors (GABA = γ-aminobutyric acid), have been synthesized. The synthesized compounds 8a-1 have been evaluated a

MECHANISTIC STUDIES OF THE UROCANASE REACTION USING (1)H- AND (31)P-NMR SPECTROSCOPY AND THE SUBSTRATE ANALOGUE 2-METHYLUROCANATE

Gerlinger, Erich,Hull, William E.,Retey, Janos

, p. 3523 - 3528 (2007/10/02)

The reaction of 2-methylurocanate with urocanase from Pseudomonas putida was monitored by (1)H-NMR spectroscopy at 500 MHz.The following conclusions were drawn: (i) 2-methylurocanate reacts 128 times more slowly with urocanase than does urocanate, (ii) no signals for the enol form of the produced 2-methylimidazolone propionate were detected, (iii) 2-methylimidazolone propionate is about 25 times more stable to hydrolysis than imidazolone propionate, (iv) the urocanase-catalysed exchange of the 5-proton of 2-methylurocanate with the solvent deuterium is 1.3 times faster than the overall reaction and (v) the non-enzymic exchange of the Me protons of 2-methylimidazolone propionate with solvent D takes place with a half life of 5.8 hr. By (1)H-NMR spectroscopy it was shown that the urocanase reaction is reversible.At 8o and pD 6.3 1.6percent of the total imidazolone propionate was converted into urocanate. Apart from the pyrophosphate ester group of NAD(1+) no phosphorylated groups could be detected in urocanase by (31)P-NMR spectroscopy.
