Check Digit Verification of cas no

The CAS Registry Mumber 1293990-07-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,3,9,9 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1293990-07:
(9*1)+(8*2)+(7*9)+(6*3)+(5*9)+(4*9)+(3*0)+(2*0)+(1*7)=194
194 % 10 = 4
So 1293990-07-4 is a valid CAS Registry Number.

Discovery of torezolid as a novel 5-hydroxymethyl-oxazolidinone antibacterial agent

Im, Weon Bin,Choi, Sun Ho,Park, Ju-Young,Choi, Sung Hak,Finn, John,Yoon, Sung-Hwa

, p. 1027 - 1039 (2011/04/17)

A series of novel substituted pyridyl phenyl oxazolidinone analogues were synthesized and their structure-activity relationship (SAR) was investigated based on in vitro and in vivo antibacterial activities. The minimum inhibitory concentrations (MICs) of the synthesized compounds against methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE) ranged from 0.12 to 2.0 μg/mL, and against Haemophilus influenzae (Hi) from 2.0 to 8.0 μg/mL. Compared to linezolid, only four compounds (11, 12, 21 and 29) showed higher in vitro antibacterial activities and better in vivo protective effects in mice. To improve the aqueous solubility, various prodrugs of compound 11 (DA-7157), which exerted a potency that was enhanced by 2-8-fold compared to that of linezolid, were synthesized. Among the prodrugs, the phosphate compound 42 exhibited excellent aqueous solubility (>50 mg/mL in DW) and good pharmacokinetic profiles, along with better in vivo efficacy than linezolid. This compound 42 is currently undergoing clinical trials with the brand name Torezolid.
