Check Digit Verification of cas no

The CAS Registry Mumber 82278-73-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,2,7 and 8 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 82278-73:
(7*8)+(6*2)+(5*2)+(4*7)+(3*8)+(2*7)+(1*3)=147
147 % 10 = 7
So 82278-73-7 is a valid CAS Registry Number.

Preparation method of lifitegrast intermediate

-

Paragraph 0047-0048, (2020/08/09)

The invention relates to a preparation method of a lifitegrast intermediate. The preparation method is implemented by the following route, has the advantages of short synthesis route, high yield and high safety, and is simple and convenient to operate and suitable for industrial production. According to the preparation method, a compound II reacts with metal zinc in an organic solvent to generatean organic zinc reagent, a compound I carries out a coupling reaction with the organic zinc reagent, a palladium reagent and a phosphorus ligand to obtain a compound III, and Boc protecting groups ofthe compound III are removed to obtain a compound IV, wherein R1 and R2 groups are respectively and independently selected from methyl, ethyl, vinyl, n-propyl, isopropyl, propenyl, propynyl, cyclopropyl, n-butyl, isobutyl, tert-butyl, butenyl, cyclobutyl, n-pentyl, iso-pentyl, cyclopentyl, n-hexyl, cyclohexyl, phenyl and benzyl.

supporting information; scheme or table, p. 203 - 206 (2012/05/04)

LFA-1/ICAM-1 interaction is essential in support of inflammatory and specific T-cell regulated immune responses by mediating cell adhesion, leukocyte extravasation, migration, antigen presentation, formation of immunological synapse, and augmentation of T-cell receptor signaling. The increase of ICAM-1 expression levels in conjunctival epithelial cells and acinar cells was observed in animal models and patients diagnosed with dry eye. Therefore, it has been hypothesized that small molecule LFA-1/ICAM-1 antagonists could be an effective topical treatment for dry eye. In this letter, we describe the discovery of a potent tetrahydroisoquinoline (THIQ)-derived LFA-1/ICAM-1 antagonist (SAR 1118) and its development as an ophthalmic solution for treating dry eye.
