Check Digit Verification of cas no

The CAS Registry Mumber 1448706-36-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,8,7,0 and 6 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1448706-36:
(9*1)+(8*4)+(7*4)+(6*8)+(5*7)+(4*0)+(3*6)+(2*3)+(1*6)=182
182 % 10 = 2
So 1448706-36-2 is a valid CAS Registry Number.

Practical Gram-Scale Synthesis of Iboxamycin, a Potent Antibiotic Candidate

Mason, Jeremy D.,Myers, Andrew G.,Pote, Aditya R.,Terwilliger, Daniel W.

supporting information, p. 11019 - 11025 (2021/08/03)

A gram-scale synthesis of iboxamycin, an antibiotic candidate bearing a fused bicyclic amino acid residue, is presented. A pivotal transformation in the route involves an intramolecular hydrosilylation-oxidation sequence to set the ring-fusion stereocenters of the bicyclic scaffold. Other notable features of the synthesis include a high-yielding, highly diastereoselective alkylation of a pseudoephenamine amide, a convergent sp3-sp2 Negishi coupling, and a one-pot transacetalization-reduction reaction to form the target compound's oxepane ring. Implementation of this synthetic strategy has provided ample quantities of iboxamycin to allow for its in vivo profiling in murine models of infection.

Scale-up Synthesis of Tesirine

Tiberghien, Arnaud C.,Von Bulow, Christina,Barry, Conor,Ge, Huajun,Noti, Christian,Collet Leiris, Florence,McCormick, Marc,Howard, Philip W.,Parker, Jeremy S.

, p. 1241 - 1256 (2018/09/06)

This work describes the enabling synthesis of tesirine, a pyrrolobenzodiazepine antibody-drug conjugate drug-linker. Over the course of four synthetic campaigns, the discovery route was developed and scaled up to provide a robust manufacturing process. Early intermediates were produced on a kilogram scale and at high purity, without chromatography. Midstage reactions were optimized to minimize impurity formation. Late stage material was produced and purified using a small number of key high-pressure chromatography steps, ultimately resulting in a 169 g batch after 34 steps. At the time of writing, tesirine is the drug-linker component of eight antibody-drug conjugates in multiple clinical trials, four of them pivotal.
