Check Digit Verification of cas no

The CAS Registry Mumber 59021-02-2 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 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 59021-02:
(7*5)+(6*9)+(5*0)+(4*2)+(3*1)+(2*0)+(1*2)=102
102 % 10 = 2
So 59021-02-2 is a valid CAS Registry Number.

COMPOUNDS AND COMPOSITIONS FOR TREATING CONDITIONS ASSOCIATED WITH APJ RECEPTOR ACTIVITY

-

, (2020/05/15)

This disclosure features chemical entities (e.g., a compound or a pharmaceutically acceptable salt and/or hydrate and/or prodrug of the compound) that modulate (e.g., agonize) the apelin receptor (also referred to herein as the APJ receptor; gene symbol APLNR). This disclosure also features compositions containing the same as well as other methods of using and making the same. The chemical entities are useful, e.g., for treating a subject (e.g., a human) having a disease, disorder, or condition in which a decrease in APJ receptor activity (e.g., repressed or impaired APJ receptor signaling; e.g., repressed or impaired apelin-APJ receptor signaling) or downregulation of endogenous apelin contributes to the pathology and/or symptoms and/or progression of the disease, disorder, or condition. Non-limiting examples of such diseases, disorders, or conditions include: (i) cardiovascular disease; (ii) metabolic disorders; (iii) diseases, disorders, and conditions associated with vascular pathology; and (iv) organ failure; (v) diseases, disorders, and conditions associated with infections (e.g., microbial infections); and (vi) diseases, disorders, or conditions that are sequela or comorbid with any of the foregoing or any disclosed herein. More particular non-limiting examples of such diseases, disorders, or conditions include pulmonary hypertension (e.g., PAH); heart failure; type II diabetes; renal failure; sepsis; and systemic hypertension.

Synthesis and Antisecretory and Antiulcer Activities of Derivatives and Analogues of 2-(2-Pyridyl)tetrahydrothiophene-2-carbothioamide

Aloup, Jean-Claude,Bouchaudon, Jean,Farge, Daniel,James, Claude,Deregnaucourt, Jean,Hardy-Houis, Monique

, p. 24 - 29 (2007/10/02)

New thioamide derivatives of 2-(2-pyridyl)tetrahydrothiophene-2-carbothioamide (29) and related compounds (in which the tetrahydrothiophene ring was replaced by tetrahydrothiopyran, tetrahydrofuran, 1,3-dithiane, or 1,3-oxathiane and where the pyridine ring was repleaced by other nitrogen heterocycles) were synthesized and tested for their antisecretory and antiulcer activities.These thioamides were prepared according to one of the following methods: (i) reaction of an isothiocyanate with the carbanion of the corresponding cyclic precursor (for secondary thioamides); (ii) reaction of ammonia or an amine with the dithio ester prepared from the same precursor (for primary, secondary, and tertiary thioamides).These thioamides were evaluated by the Shay method to measure their antisecretory activity and by the stress-induced-ulcer method to test their antiulcer activity.Structure-activity relationships are discussed.N-Methyl-2-(2-pyridyl)tetrahydrothiophene-2-carbothioamide (R.P. 40749,30) exhibited activities that were at least 10 times higher than those reported for cimetidine.
