Check Digit Verification of cas no

The CAS Registry Mumber 5431-93-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,3 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5431-93:
(6*5)+(5*4)+(4*3)+(3*1)+(2*9)+(1*3)=86
86 % 10 = 6
So 5431-93-6 is a valid CAS Registry Number.

Synthesis of a Precursor of the Antiviral Agent A-315675

Egorov,Gimalova

, p. 241 - 244 (2019/05/01)

Ethyl 2-(acetylamino)-3-methoxy-3-methylhexanoate, a key precursor of the known pyrrolidine antiviral agent A-315675, was synthesized starting with the readily available acetoacetic ester.

Rhodium-catalyzed asymmetric hydrogenation of tetrasubstituted β-acetoxy-α-enamido esters and efficient synthesis of droxidopa

Guan, Yu-Qing,Gao, Min,Deng, Xu,Lv, Hui,Zhang, Xumu

supporting information, p. 8136 - 8139 (2017/07/24)

A rhodium-catalyzed asymmetric hydrogenation of challenging tetrasubstituted β-acetoxy-α-enamido esters was developed, giving chiral β-acetoxy-α-amido esters in high yields with excellent enantioselectivities (up to >99% ee). The products could be easily transformed to β-hydroxy-α-amino acid derivatives which are valuable chiral building blocks and a novel route for the synthesis of droxidopa was also developed.

Nonpeptidic Selective Inhibitors of the Chymotrypsin-Like (β5 i) Subunit of the Immunoproteasome

Sosi?, Izidor,Gobec, Martina,Brus, Boris,Knez, Damijan,?ivec, Matej,Konc, Janez,Le?nik, Samo,Ogrizek, Mitja,Obreza, Ale?,?igon, Du?an,Jane?i?, Du?anka,Mlinari?-Ra??an, Irena,Gobec, Stanislav

supporting information, p. 5745 - 5748 (2016/05/09)

Elevated expression of the immunoproteasome has been associated with autoimmune diseases, inflammatory diseases, and various types of cancer. Selective inhibitors of the immunoproteasome are not only scarce, but also almost entirely restricted to peptide-based compounds. Herein, we describe nonpeptidic reversible inhibitors that selectively block the chymotrypsin-like (β5i) subunit of the human immunoproteasome in the low micromolar range. The most potent of the reversibly acting compounds were then converted into covalent, irreversible, nonpeptidic inhibitors that retained selectivity for the β5i subunit. In addition, these inhibitors discriminate between the immunoproteasome and the constitutive proteasome in cell-based assays. Along with their lack of cytotoxicity, these data point to these nonpeptidic compounds being suitable for further investigation as β5i-selective probes for possible application in noncancer diseases related to the immunoproteasome.
