Check Digit Verification of cas no

The CAS Registry Mumber 56057-19-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,0,5 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 56057-19:
123 % 10 = 3
So 56057-19-3 is a valid CAS Registry Number.

Phenacylation of 6-methyl-beta-nitropyridin-2-ones and further heterocyclization of products

Babaev, Eugene V.,Rybakov, Victor B.

, (2020/04/17)

Reaction between the derivatives of 6-methyl-beta-nitropyridin-2-one and phenacyl bromides was studied, and the yields observed were extremely low. The pyridones were converted via chloropyridines to methoxyderivatives, which were N-phenacylated. N-Phenacyl derivatives of 4,6-dimethyl-5-nitropyridin-2-one under the action of base gave 5-hydroxy-8-nitroindolizine and under acidic conditions gave 5-methyl-6-nitrooxazole[3,2-a]pyridinium salt, which underwent recycization with MeONa to 5-methoxy-8-nitroindolizine.

Structure-activity relationships of a series of pyrrolo[3,2-d]pyrimidine derivatives and related compounds as neuropeptide Y5 receptor antagonists


, p. 4288 - 4312 (2007/10/03)

Neuropeptide Y (NPY) has been shown to play an important role in the regulation of food intake and energy balance. Pharmacological data suggests that the Y5 receptor subtype contributes to the effects of NPY on appetite, and therefore a Y5 antagonist might be a useful therapeutic agent for the treatment of obesity. In attempts to identify potential Y5 antagonists, a series of pyrrolo[3,2-d]pyrimidine derivatives was prepared and evaluated for their ability to bind to Y5 receptors in vitro. We report here the synthesis and initial structure-activity relationship investigations for this class of compounds. The target compounds were prepared by a variety of synthetic routes designed to modify both the substitution and the heterocyclic core of the pyrrolo[3,2-d]pyrimidine lead 1. In addition to identifying several potent Y5 antagonists for evaluation as potential antiobesity agents, a pharmacophore model for the human Y5 receptor is presented.

Pyrido[3,2-e][1,4]diazepines - Synthesis and anti-HIV-1-activity tests


, p. 247 - 255 (2007/10/02)

Starting from the commercially available 6-methyl-2-pyridylamine (1) the pyrido[3,2-e][1,4]diazepine 14a was synthesized in 12 steps with 7% total yield. 14a, the N-methyl derivative 14b, the thiolactam 15a, the amidine 16, and the 1,2,4-triazole 17 were tested for anti-HIV-1-activity. None of the compounds tested possesses antiviral activity comparable to that of zidovudine (3'-azido-3'-desoxythymidine = AZT).
