Check Digit Verification of cas no

The CAS Registry Mumber 4877-23-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,7 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4877-23:
(6*4)+(5*8)+(4*7)+(3*7)+(2*2)+(1*3)=120
120 % 10 = 0
So 4877-23-0 is a valid CAS Registry Number.

Switching Lysophosphatidylserine G Protein-Coupled Receptor Agonists to Antagonists by Acylation of the Hydrophilic Serine Amine

Sayama, Misa,Uwamizu, Akiharu,Ikubo, Masaya,Chen, Luying,Yan, Ge,Otani, Yuko,Inoue, Asuka,Aoki, Junken,Ohwada, Tomohiko

, p. 10059 - 10101 (2021/07/28)

Three human G protein-coupled receptors (GPCRs)—GPR34/LPS1, P2Y10/LPS2, and GPR174/LPS3—are activated specifically by lysophosphatidylserine (LysoPS), an endogenous hydrolysis product of a cell membrane component, phosphatidylserine (PS). LysoPS consists of-serine, glycerol, and fatty acid moieties connected by phosphodiester and ester linkages. We previously generated potent and selective GPCR agonists by modification of the three modules and the ester linkage. Here, we show that a novel modification of the hydrophilic serine moiety, that is, N-acylations of the serine amine, converted a GPR174 agonist to potent GPR174 antagonists. Structural exploration of the amide functionality provided access to a range of activities from agonist to partial agonist to antagonist. The present study would provide a new strategy for the development of lysophospholipid receptor antagonists.

Chemical pyrophosphorylation of functionally diverse peptides

Marmelstein, Alan M.,Yates, Lisa M.,Conway, John H.,Fiedler, Dorothea

supporting information, p. 108 - 111 (2014/01/23)

A highly selective and convenient method for the synthesis of pyrophosphopeptides in solution is reported. The remarkable compatibility with functional groups (alcohol, thiol, amine, carboxylic acid) in the peptide substrates suggests that the intrinsic nucleophilicity of the phosphoserine residue is much higher than previously appreciated. Because the methodology operates in polar solvents, including water, a broad range of pyrophosphopeptides can be accessed. We envision these peptides will find widespread applications in the development of mass spectrometry and antibody-based detection methods for pyrophosphoproteins.
