Check Digit Verification of cas no

The CAS Registry Mumber 81167-39-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,1,6 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81167-39:
(7*8)+(6*1)+(5*1)+(4*6)+(3*7)+(2*3)+(1*9)=127
127 % 10 = 7
So 81167-39-7 is a valid CAS Registry Number.

Synthesis of fluorescent dipeptidomimetics and their ribosomal incorporation into green fluorescent protein

Roy Chowdhury, Sandipan,Maini, Rumit,Dedkova, Larisa M.,Hecht, Sidney M.

, p. 4715 - 4718 (2015)

The synthesis and incorporation into position 66 of green fluorescent protein (GFP) by in vitro protein translation of novel oxazole and thiazole based dipeptidomimetics are described. The compounds may be regarded as GFP chromophore analogues, and are strongly fluorescent. An α-amido-β-ketoester intermediate was obtained via bisacylation of a protected glycine. The intermediate underwent dehydrative cyclization to afford the 1,3-oxazole and was treated with Lawesson's reagent to furnish the 1,3-thiazole. When these fluorophores were introduced into position 66 of GFP in place of Tyr66, the resulting GFP analogues exhibited fluorescence emission several-fold greater than wild-type GFP; the emission was also shifted to shorter wavelength. It may be noted that compared to the typical fluorophores formed in the natural and modified fluorescent proteins, the oxazole and thiazole fluorophores are completely stable and do not require activation by posttranslational modification to exhibit fluorescence.

Synthesis of β-Hydroxy α-Amino Acids through Br?nsted Base-Catalyzed syn-Selective Direct Aldol Reaction of Schiff Bases of Glycine o-Nitroanilide

Vera, Silvia,Vázquez, Ana,Rodriguez, Ricardo,Pozo, Sandra Del,Urruzuno, I?aki,de Cózar, Abel,Mielgo, Antonia,Palomo, Claudio

, p. 7757 - 7772 (2021/06/21)

Here we report the highly enantio- and syn-selective synthesis of β-hydroxy α-amino acids from glycine imine derivatives under Br?nsted base (BB) catalysis. The key of this approach is the use of benzophenone-derived imine of glycine o-nitroanilide as a pronucleophile, where the o-nitroanilide framework provides an efficient hydrogen-bonding platform that accounts for nucleophile reactivity and diastereoselectivity.

A fully stereoselective synthesis of unnatural chiral β-aryl-β-pyrazolyl α-amino acid esters via copper-catalyzed addition reactions of azomethine ylides with benzylidenepyrazolones bearing two contiguous stereogenic centers was developed. A 1H-pyrazol-5-ol was introduced by the aromatization of 3H-pyrazol-3-one in the reaction. The transformation operated at room temperature and afforded β-1H-pyrazol-5-ol-α-amino esters in high yields with good to excellent levels of diastereo- and enantioselectivity.
