1431461-34-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1431461-34-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,1,4,6 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1431461-34:
(9*1)+(8*4)+(7*3)+(6*1)+(5*4)+(4*6)+(3*1)+(2*3)+(1*4)=125
125 % 10 = 5
So 1431461-34-5 is a valid CAS Registry Number.

Toward waste-free peptide synthesis using ionic reagents and ionic liquids as solvents
Galy, Nicolas,Mazières, Marie-Rose,Plaquevent, Jean-Christophe
, p. 2703 - 2705 (2013)
CBEIT 1, an ionic coupling reagent, gives access to amino acid carbamates, and allows waste-free peptide coupling. The only by-products are carbon dioxide and ethylimidazolium triflate that is an ionic liquid playing the role of the solvent.
