164931-20-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 164931-20-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,4,9,3 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 164931-20:
(8*1)+(7*6)+(6*4)+(5*9)+(4*3)+(3*1)+(2*2)+(1*0)=138
138 % 10 = 8
So 164931-20-8 is a valid CAS Registry Number.

Nitroxide derivative of ROCK kinase inhibitor

-

Paragraph 0242-0248, (2020/06/17)

The invention provides a small molecular compound of a NO donor. The small molecular compound is characterized in that the small molecular compound is a compound shown represented by structural formula I shown in the description, or a stereoisomer, a geometrical isomer, a tautomer, a racemate, a deuterated isotope derivative, a hydrate, a solvate, a metabolite, a pharmaceutically acceptable salt or a prodrug thereof; and in the formula I, ring A is a substituted or unsubstituted heteroaromatic ring, X is selected from (CH2)n, n is selected from 0, 1, 2 and 3, R is a substituent group of terminal -O-NO2, R is selected from hydrogen, a hydroxyl group, halogen, an amino group, a cyano group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkynyl group and a substituted or unsubstituted heteroalkyl group, and R and R are respectively and independently selected from hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted naphthenic base or an amino protecting group, or R and R are connected to form a substituted or unsubstituted cyclic heteroalkyl group. The compound has a high-activity inhibition effect on ROCK kinase.

Page/Page column 39, (2010/11/25)

Substituted 5-aryl-2,4-thiazolidinediones are potent agonists of PPAR, and are therefore useful in the treatment, control or prevention of diabetes, hyperglycemia, hyperlipidemia (including hypercholesterolemia and hypertriglyceridemia), atherosclerosis, obesity, vascular restenosis, and other PPAR alpha , delta and/or gamma mediated diseases, disorders and conditions.

COMPOUNDS HAVING β2 ADRENERGIC RECEPTOR AGONIST AND MUSCARINIC RECEPTOR ANTAGONIST ACTIVITY

-

Page/Page column 75, (2008/06/13)

This invention provides compounds of formula I wherein R1, R2, R3, R4, R5, R6, R7, R8a, R8b, W, a and b are as defined in the specification, or a pharmaceutically acceptable salt or solvate or stereoisomer thereof. The compounds of this invention possess both β2 adrenergic receptor agonist and muscarinic receptor antagonist activity. Accordingly, such compounds are expected to be useful as therapeutic agents for treating pulmonary disorders, such as chronic obstructive pulmonary disease and asthma.
