Check Digit Verification of cas no

The CAS Registry Mumber 103450-87-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,4,5 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 103450-87:
(8*1)+(7*0)+(6*3)+(5*4)+(4*5)+(3*0)+(2*8)+(1*7)=89
89 % 10 = 9
So 103450-87-9 is a valid CAS Registry Number.

3-keto-9-O-substituted oxime derivatives of 6-O-methyl erythromycin A synthesis and in vitro activity

Shengxi,Xiandong,Lanxiang

, p. 506 - 509 (2001)

A series of 3-keto-9-O-substituted oxime derivatives of 6-O-methyl erythromycin A were prepared with a novel synthetic route, which include 6 reaction steps-oximation, protection, hydrolysis, oxidation, deprotection and addition. The antibacterial activit

Synthesis and antibacterial activity of novel 3-O-arylalkylcarbamoyl-3-O-descladinosyl-9-O-(2-chlorobenzyl)oxime clarithromycin derivatives

Qin, Yinhui,Qiang, Shengsheng,Ji, Shengli,Liu, Zhiyang,Hu, Chaoyu,Ma, Shutao

, p. 3324 - 3328 (2018)

A novel series of 3-O-arylalkylcarbamoyl-3-O-descladinosyl-9-O-(2-chlorobenzyl)oxime clarithromycin derivatives, were designed, synthesized and evaluated for their in vitro antibacterial activity. These derivatives were found to have strong activity against susceptible and resistant bacteria strains. Among them, compounds 7a and 7q showed the most potent activity (0.125 μg/mL) against erythromycin-resistant S. pneumoniae expressing the mefA gene. Moreover, compounds 7f, 7i, 7p and 7z displayed remarkably improved activity (4 μg/mL) against penicillin-resistant S. aureus ATCC31007, and compounds 7a, 7b, 7f, 7p and 7z showed improved activity (8 μg/mL) against erythromycin-resistant S. pyogenes. In particular, compound 7z exhibited potent and balanced activity against the tested drug-susceptible and -resistant bacterial strains.

PROCESS FOR THE PREPARATION OF 6-O-METHYLERYTHROMYCIN A 9-OXIME

-

Page/Page column 6, (2009/03/07)

The present invention relates to process for the preparation of 6-O-methylerythromycin A 9-oxime by treating 6-O-methylerythromycin A with hydroxyl amine hydrochloride in the presence of a base and a solvent.

CHEMICAL MODIFICATION OF ERYTHROMYCINS. VIII. A NEW EFFECTIVE ROUTE TO CLARITHROMYCIN (6-O-METHYLERYTHROMYCIN A)

Watanabe, Yoshiaki,Adachi, Takashi,Asaka, Toshifumi,Kashimura, Masato,Morimoto, Shigeo

, p. 2121 - 2124 (2007/10/02)

Selective O-methylation of the C-6 hydroxyl group of erythromycin A could be satisfactorily achieved by using its 9-oxime derivatives as the starting materials.Thus, 6-O-methylerythromycin A (clarithromycin) was synthesized from 2'-O-,3'-N-bis(benzyloxycarbonyl)-N-demethylerythromycin A via its 9-oxime derivative by 6 steps.
