Check Digit Verification of cas no

The CAS Registry Mumber 893643-73-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,3,6,4 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 893643-73:
(8*8)+(7*9)+(6*3)+(5*6)+(4*4)+(3*3)+(2*7)+(1*3)=217
217 % 10 = 7
So 893643-73-7 is a valid CAS Registry Number.

-

Paragraph 0222-0223; 0224-0226, (2020/07/29)

The invention belongs to the technical field of medicinal chemistry, and particularly relates to lysophosphatidic acid receptor antagonists and a preparation method thereof. The applicant surprisinglyfinds that compounds provided by the invention have high LPAR1 antagonistic activity and selectivity, low toxicity, good metabolic stability and good drug development prospect, and can be used for preventing or treating diseases or symptoms related to LPAR1. The applicant also accidentally finds that the IC50 value of part of the compounds can be as low as 300 nM or below and even 50 nM or below.Moreover, the compounds disclosed by the invention have better safety, and the CC50 range of the compounds can reach 200 [mu]M or above. In addition, the compounds of the present invention have goodmetabolic stability in humans, rats, and mice, such excellent inhibitory activity being very desirable for their use as LPAR1 inhibitors in the above diseases or disorders. In addition, the preparation method of the compounds is simple, mild in reaction condition, high in product yield and suitable for industrial production.

Aminoacetamide acyl guanidines as beta-secretase inhibitors

-

Page/Page column 31, (2008/06/13)

There is provided a series of substituted acyl guanidines of Formula (Ik) or a stereoisomer; or a pharmaceutically acceptable salt thereof, wherein R2, R3, R4, R5, R25, R26 and R27 as defined herein, their pharmaceutical compositions and methods of use. These compounds inhibit the processing of amyloid precursor protein (APP) by β-secretase and, more specifically, inhibit the production of Aβ-peptide. The present disclosure is directed to compounds useful in the treatment of neurological disorders related to β-amyloid production, such as Alzheimer's disease and other conditions affected by anti-amyloid activity.
