Check Digit Verification of cas no

The CAS Registry Mumber 76792-22-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,7,9 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 76792-22:
(7*7)+(6*6)+(5*7)+(4*9)+(3*2)+(2*2)+(1*2)=168
168 % 10 = 8
So 76792-22-8 is a valid CAS Registry Number.

A novel lipase from Aspergillus oryzae catalyzed resolution of (R,S)-ethyl 2-bromoisovalerate

Wu, Peng,Zhang, Mengjie,Zhang, Yinjun,Wang, Zhao,Zheng, Jianyong

, p. 231 - 238 (2019/12/27)

In this study, a novel lipase M5 derived from Aspergillus oryzae WZ007 was prone to exhibit high hydrolytic activity and stereoselectivity towards racemic substrate (R,S)-ethyl 2-bromoisovalerate. (R)-ethyl 2-bromoisovalerate was obtained by enzymatic resolution, which is the key chiral intermediate for highly efficient enantiomerically fluvalinate. The results showed that the enzymatic reaction was carried out in 120mM racemic substrate for 3 hours, the enantiomeric excess reached 98.6%, the conversion was 51.7%, and E value above 120. Therefore, the novel lipase M5 has the ability to efficiently produce (R)-ethyl 2-bromoisovalerate, which greatly reduces the industrial production cost of the highly efficient counterpart of fluvalinate.

Solid phase synthesis of 1,3,4-oxadiazin-5 (6R)-one and 1,3,4-oxadiazol-2-one scaffolds from acyl hydrazides

Sarma, Bani Kanta,Liu, Xiaodan,Wu, Hao,Gao, Yu,Kodadek, Thomas

supporting information, p. 59 - 63 (2015/02/02)

Solid phase synthesis of 1,3,4-oxadiazin-5(6R)-one and 1,3,4-oxadiazol-2-one scaffolds from resin-bound acyl hydrazides is described. We demonstrate here that the reactions of resin-bound aryl or hetero-aromatic acyl hydrazides with 2-substituted-2-bromoacetic acids and 4-nitrophenyl chloroformate and subsequent treatment with DIEA lead to intramolecular cyclization reactions to produce six-membered 1,3,4-oxadiazin-5(6R)-ones and five-membered 1,3,4-oxadiazol-2-ones, respectively. We also show that acyl hydrazide-derived 1,3,4-oxadiazol-2-ones may be useful serine hydrolase inhibitors. This journal is

A novel series of parenteral cephalosporins exhibiting potent activities against Pseudomonas aeruginosa and other Gram-negative pathogens: Synthesis and structure-activity relationships

Yamawaki, Kenji,Nomura, Takashi,Yasukata, Tatsuro,Uotani, Koichi,Miwa, Hideaki,Takeda, Kei,Nishitani, Yasuhiro

, p. 6716 - 6732 (2008/03/28)

A series of 7β-[2-(2-aminothiazol-4-yl)-2-(Z)-(carboxymethoxyimino)acetamido]cephalosporins bearing a 1-(substituted)-1H-pyrrolo[3,2-b]pyridinium group at C-3′ position was synthesized and their in vitro antibacterial activities against Pseudomonas aeruginosa and other Gram-negative pathogens were evaluated. Among the cephalosporins prepared, 7β-[2-(2-amino-5-chlorothiazol-4yl)-2(Z)-((S)-1-carboxyethoxyimino)acetamido]cephalosporins (42d) showed potent antibacterial activities against P. aeruginosa and other Gram-negative pathogens including the strains which produce class C β-lactamase and extended spectrum β-lactamase (ESBL). These results imply that both the Cl atom on the C-7 aminothiazole moiety and the α-substituent at the iminoether moiety are essential for the stability against β-lactamase and the potent activity against Gram-negative bacteria including P. aeruginosa.
