Check Digit Verification of cas no

The CAS Registry Mumber 77474-14-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,4,7 and 4 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 77474-14:
(7*7)+(6*7)+(5*4)+(4*7)+(3*4)+(2*1)+(1*4)=157
157 % 10 = 7
So 77474-14-7 is a valid CAS Registry Number.

Neurogenic and neuroprotective donepezil-flavonoid hybrids with sigma-1 affinity and inhibition of key enzymes in Alzheimer's disease

Estrada Valencia, Martín,Herrera-Arozamena, Clara,de Andrés, Lucía,Pérez, Concepción,Morales-García, José A.,Pérez-Castillo, Ana,Ramos, Eva,Romero, Alejandro,Vi?a, Dolores,Yá?ez, Matilde,Laurini, Erik,Pricl, Sabrina,Rodríguez-Franco, María Isabel

supporting information, p. 534 - 553 (2018/07/25)

In this work we describe neurogenic and neuroprotective donepezil-flavonoid hybrids (DFHs), exhibiting nanomolar affinities for the sigma-1 receptor (σ1R) and inhibition of key enzymes in Alzheimer's disease (AD), such as acetylcholinesterase (AChE), 5-lipoxygenase (5-LOX), and monoamine oxidases (MAOs). In general, new compounds scavenge free radical species, are predicted to be brain-permeable, and protect neuronal cells against mitochondrial oxidative stress. N-(2-(1-Benzylpiperidin-4-yl)ethyl)-6,7-dimethoxy-4-oxo-4H-chromene-2-carboxamide (18) is highlighted due to its interesting biological profile in σ1R, AChE, 5-LOX, MAO-A and MAO-B. In phenotypic assays, it protects a neuronal cell line against mitochondrial oxidative stress and promotes maturation of neural stem cells into a neuronal phenotype, which could contribute to the reparation of neuronal tissues. Molecular modelling studies of 18 in AChE, 5-LOX and σ1R revealed the main interactions with these proteins, which will be further exploited in the optimization of new, more efficient DFHs.

Synthesis of 2-(4-isopropylthiazol-2-yl)-7-methoxy-8-methylquinolin-4-ol; A quinoline building block for simeprevir synthesis

Rádl, Stanislav,Rezková, Hana,Obadalová, Iva,Srbek, Jan,B?ichá?, Ji?í,Pekárek, Tomá?

, p. 899 - 908 (2014/04/03)

Two synthetic approaches to the achiral quinoline fragment of simeprevir are described. Both approaches are based on the synthesis of methyl 4-hydroxy-7-methoxy-8-methylquinoline-2-carboxylate, protection of its 4-hydroxyl group, and construction of the thiazole ring from the ester group at the 2-position. The last step is acid deprotection of the 4-hydroxyl protecting group. Georg Thieme Verlag Stuttgart. New York.
