312746-55-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 312746-55-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,2,7,4 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 312746-55:
(8*3)+(7*1)+(6*2)+(5*7)+(4*4)+(3*6)+(2*5)+(1*5)=127
127 % 10 = 7
So 312746-55-7 is a valid CAS Registry Number.

Facile chemoselective synthesis of dehydroalanine-containing peptides.
Okeley,Zhu,van Der Donk
, p. 3603 - 3606 (2007/10/03)
Useful methodology is described for the synthesis of dehydroalanine residues (II) within peptides. The unnatural amino acid (Se)-phenylselenocysteine (I) can be incorporated into growing peptide chains via standard peptide synthesis procedures. Subsequent
