Check Digit Verification of cas no

The CAS Registry Mumber 3304-51-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,0 and 4 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3304-51:
(6*3)+(5*3)+(4*0)+(3*4)+(2*5)+(1*1)=56
56 % 10 = 6
So 3304-51-6 is a valid CAS Registry Number.

A high optical activity chiral sea natural product synthesis method

-

Paragraph 0055; 0056, (2017/08/25)

The invention discloses a synthetic method for a chiral marine natural product with high optical activity. According to the method, a marine natural product with the high optical activity is prepared by adopting chiral amino acid. The method specifically comprises the following steps: first, using L-ornithine monohydrochloride and D-ornithine monohydrochloride as starting raw materials, and performing copper ion complexing, amino protecting, esterifying, urea forming and cyclizing to obtain an intermediate 5; then, using N-methylpyrrole as a raw material, and performing electrophilic reaction, hydrolyzing, acidizing and acylating in sequence to obtain an intermediate 9; finally, enabling the intermediate 5 and the intermediate 9 to react to prepare corresponding chiral natural products, namely (S)-midpacamide or (R)-midpacamide. According to the synthetic method, synthetic steps are simple; the operation is simple and convenient; reaction conditions are mild; the original structure of the product prepared by the provided synthetic route is kept; the optical purity of the obtained marine natural product is greater than 99 percent; the marine natural product has a wide application prospect.

Selection of amino acids and the biomimetic synthesis of amido bond in the presence of β-CD

Su, Jie,Su, Fan,Ma, MingFang,Li, Shangyang,Xing, Pengyao,Hao, Aiyou

, p. 1111 - 1121 (2014/04/03)

A new method was developed to construct a special amido bond in the presence of β-cyclodextrin. This process is similar to peptide synthesis in organisms. NMR experiments were performed to investigate the possible mechanism. This work has potential application in biomimetic peptide synthesis.

Decomposition of copper-amino acid complexes by oxalic acid dihydrate

Liu, Yi,Jia, Genguang,Ling, Xin,Lan, Nuo,Zheng, Youguang,Li, Sai,Zhang, Ling,Liu, Ling,Zhang, Rongli,Xue, Yunsheng

experimental part, p. 557 - 559 (2012/08/08)

A facile approach to the synthesis of some side-chain-protected amino acids via oxalic acid dihydrate as the copper sequestering reagent is presented. The copper in the amino acid complex reacted with oxalic acid dihydrate to form insoluble cupric oxalate, with the free amino acid released. Compared with conventional methods, this method is convenient, inexpensive, and environmentally friendly.

Ca2+-induced folding of a chiral ditopic receptor based on a Pybox ligand and enhancement of anion recognition

Yamamura, Masaki,Miyake, Junya,Imamura, Yuki,Nabeshima, Tatsuya

supporting information; scheme or table, p. 6801 - 6803 (2011/09/12)

A chiral Pybox ligand bearing two urea units was developed for a Ca 2+-induced folding ligand. 11 Ca2+ complexation of the Pybox ligand afforded chiral foldamer formation with coordination of the urea carbonyls to Ca2+. The halide-ion affinity of the foldamer was enhanced compared to Ca2+-free Pybox ligands.

Selective [15Nη2] labelling of an NG-propionylated arginine derivative

Kleinmaier, Roland,Gschwind, Ruth M.

experimental part, p. 29 - 32 (2009/10/23)

A straightforward convergent synthesis of [15N η2]-Bz-Arg(Nη-propionyl)-OEt*TFA is presented. In this approach, the guanidinylation reagent [15N 2]-N(boc)-N′(propionyl)-S-methylisothiourea is reacted with the side chain amino group of the title compound's ornithine precursor. The guanidinylation step is promoted by stoichiometric addition of HgCl2 to force completion. This method leads directly to the NG-acylated product and the acyl residue is principally modifiable in the last synthetic step of the guanidinylation reagent. Copyright

Decomposition of copper-amino acid complexes by sodium sulfide

Nowshuddin, Shaik,Reddy, A. Ram

, p. 5159 - 5161 (2007/10/03)

Sodium sulfide very efficiently removes copper from protected amino acid-copper complexes. The copper in the amino acid complex was reduced to insoluble cuprous sulfide and the free amino acid was released in pure form. This method is very convenient and rapid, requiring only 5-10 min and 0.55-0.75 equiv of sodium sulfide.
