57791-42-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 57791-42-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,7,9 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 57791-42:
(7*5)+(6*7)+(5*7)+(4*9)+(3*1)+(2*4)+(1*2)=161
161 % 10 = 1
So 57791-42-1 is a valid CAS Registry Number.

Mechanism study on the oligomerization of amino acids into peptides by phosphorus trichloride

Zhao, Wenjie,Zhao, Dongxin,Lu, Kui

scheme or table, p. 691 - 698 (2009/05/07)

As treated by phosphorus trichloride, amino acids could oligomerize into polypeptides. Based on the results obtained by 31P-NMR and ESI-MS/MS, a possible reaction mechanism was proposed. The mechanism might undergo a penta-coordinated phosphorus intermediat. The activated amino acid was a five-membered cyclic penta-coordinated phosphorus intermediate. The nucleophilic attack of the amino group from an amino acid or peptide on the carbonyl group of intermediate led to the formation of peptide and released one equivalent dichloride phosphoric acid. The repetition of the reaction sequence generated a series of oligopeptides. Copyright Taylor & Francis Group, LLC.
