Check Digit Verification of cas no
The CAS Registry Mumber 913835-76-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,3,8,3 and 5 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 913835-76:
(8*9)+(7*1)+(6*3)+(5*8)+(4*3)+(3*5)+(2*7)+(1*6)=184
184 % 10 = 4
So 913835-76-4 is a valid CAS Registry Number.

The present invention relates to methods of preparing benzoxaboroles. Benzoxaborole compounds have shown promise as antimicrobial agents, especially against fungal pathogens. The invention also relates to compositions of acyclic alkoxy boronic acid esters as intermediates, and continuous flow processes of mixing the intermediates with organomagnesium, magnesium, or organolithium reagents to form the desired benzoxaboroles.

Chiral 3-substituted benzoxaboroles were designed as carbapenemase inhibitors and efficiently synthesisedviaasymmetric Morita-Baylis-Hillman reaction. Some of the benzoxaboroles were potent inhibitors of clinically relevant carbapenemases and restored the activity of meropenem in bacteria harbouring these enzymes. Crystallographic analyses validate the proposed mechanism of binding to carbapenemases,i.e.in a manner relating to their antibiotic substrates. The results illustrate how combining a structure-based design approach with asymmetric catalysis can efficiently lead to potent β-lactamase inhibitors and provide a starting point to develop drugs combatting carbapenemases.
