342904-04-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 342904-04-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,2,9,0 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 342904-04:
(8*3)+(7*4)+(6*2)+(5*9)+(4*0)+(3*4)+(2*0)+(1*4)=125
125 % 10 = 5
So 342904-04-5 is a valid CAS Registry Number.

Synthesis of a selenocysteine-containing peptide by native chemical ligation

Gieselman, Matt D.,Xie, Lili,Van Der Donk, Wilfred A.

, p. 1331 - 1334 (2007/10/03)

(equation presented) A new method for the synthesis of selenocysteine derivatives and selenocysteine-containing peptides is described. Fmoc-Se-p-methoxybenzylselenocysteine (1) was prepared and used for solid-phase synthesis of peptides with an N-terminal unprotected selenocysteine. Subsequent native chemical ligation with a peptide thioester provided a 17-mer that corresponds to the C-terminus of ribonucleotide reductase with selenocysteine in place of cysteine.
