Check Digit Verification of cas no

The CAS Registry Mumber 34306-42-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,3,0 and 6 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 34306-42:
(7*3)+(6*4)+(5*3)+(4*0)+(3*6)+(2*4)+(1*2)=88
88 % 10 = 8
So 34306-42-8 is a valid CAS Registry Number.

Enantioselective Deaminative Alkylation of Amino Acid Derivatives with Unactivated Olefins

Cai, Yue-Ming,Martin, Ruben,Rui, Xi-Yan,Shang, Ming,Sun, Shang-Zheng,Wang, Jia-Bao,Yao, Hong-Qing,Zhang, De-Liang

supporting information, p. 1130 - 1137 (2022/02/05)

Herein, we report the first Ni-catalyzed enantioselective deaminative alkylation of amino acid and peptide derivatives with unactivated olefins. Key for success was the discovery of a new sterically encumbered bis(oxazoline) ligand backbone, thus offering a de novo technology for accessing enantioenriched sp3-sp3 linkages via sp3 C-N functionalization. Our protocol is distinguished by its broad scope and generality across a wide number of counterparts, even in the context of late-stage functionalization. In addition, an enantioselective deaminative remote hydroalkylation reaction of unactivated internal olefins is within reach, thus providing a useful entry point for forging enantioenriched sp3-sp3 centers at remote sp3 C-H sites.

Biocatalytic Cascade Reaction for the Asymmetric Synthesis of L- and D-Homoalanine

Silva, Marcus V. de M.,Costa, Ingrid C. R.,de Souza, Rodrigo O. M. A.,Bornscheuer, Uwe T.

, p. 407 - 411 (2018/11/01)

Unnatural amino acids attract growing attention for pharmaceutical applications as they are useful building blocks for the synthesis of a number of chiral drugs. Here, we describe a two-step enzymatic method for the asymmetric synthesis of homoalanine from L-methionine, a cheap and readily available natural amino acid. First, the enzyme L-methionine γ-lyase (METase), from Fusobacterium nucleatum, catalyzed the γ-elimination of L-methionine to 2-oxobutyrate. Second, an amino acid aminotransferase catalyzed the asymmetric conversion of 2-oxobutyrate to either L- or D-homoalanine. The L-branched chain amino acid aminotransferase from Escherichia coli (eBCAT), using L-glutamate as amino donor, produced L-homoalanine (32.5 % conv., 28 % y, 99 % ee) and the D-amino acid aminotransferase from Bacillus sp. (DATA) used D-alanine as amino donor to produce D-homoalanine (87.5 % conv., 69 % y, 90 % ee). Thus, this concept allows for the first time the synthesis of both enantiomers of this important unnatural amino acid.

HETEROARYL DERIVATIVE OR PHARMACEUTICALLY ACCEPTABLE SALT THEREOF, PREPARATION METHOD THEREFOR, AND PHARMACEUTICAL COMPOSTION FOR PREVENTING OR TREATING DISEASES ASSOCIATED WITH PI3 KINASES, CONTAINING SAME AS ACTIVE INGREDIENT

-

Paragraph 0553-0556, (2018/04/26)

The present invention relates to a heteroaryl derivative or a pharmaceutically acceptable salt thereof, a preparation method therefor, and a pharmaceutical composition for preventing or treating diseases associated with PI3 kinases, containing the same as an active ingredient. The heteroaryl derivative according to the present invention has an excellent effect of selectively inhibiting PI3 kinases, thereby being useful in preventing or treating PI3 kinase diseases such as: cancers, autoimmune diseases, and respiratory diseases.
