1253278-93-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1253278-93-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,3,2,7 and 8 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1253278-93:
(9*1)+(8*2)+(7*5)+(6*3)+(5*2)+(4*7)+(3*8)+(2*9)+(1*3)=161
161 % 10 = 1
So 1253278-93-1 is a valid CAS Registry Number.

Synthesis and antibacterial activity of novel 4″-O-carbamoyl erythromycin-A derivatives

Qi, Yunkun,Jiao, Bo,Ma, Xiaodong,Cui, Wenping,Ma, Shutao

, p. 458 - 464 (2011/04/16)

Novel 4″-O-carbamoyl erythromycin-A derivatives were designed, synthesized, and evaluated for their in-vitro antibacterial activities. All of the 4″-O-carbamoyl derivatives showed excellent activity against erythromycin-susceptible Staphylococcus aureus ATCC25923, Streptococcus pyogenes, and Streptococcus pneumoniae ATCC49619. Most of the 4″-O-arylalkylcarbamoyl derivatives displayed potent activity against erythromycin-resistant S. pneumoniae encoded by the mef gene and greatly improved activity against erythromycin-resistant S. pneumoniae encoded by the erm gene or the erm and mef genes. In particular, the 4″-O-arylalkyl derivatives 4c-4e and 4g were found to possess the most potent activity against all the tested erythromycin-susceptible strains, which were comparable to those of erythromycin, clarithromycin, or azithromycin. 4″-O-Arylalkyl derivatives 4e and 4g were the most effective against erythromycin-resistant S. pneumoniae encoded by the mef gene (0.25 and 0.25 μg/mL). 4″-O-Arylalkyl derivatives 4a and 4b exhibited significantly improved activity against erythromycin-resistant S. pneumoniae encoded by the erm gene. In contrast, the 4″-O-alkylcarbamoyl derivatives hardly showed improved activity against all the tested erythromycin-resistant strains.
