1273503-57-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1273503-57-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,3,5,0 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1273503-57:
(9*1)+(8*2)+(7*7)+(6*3)+(5*5)+(4*0)+(3*3)+(2*5)+(1*7)=143
143 % 10 = 3
So 1273503-57-3 is a valid CAS Registry Number.

Stereoselective palladium-catalyzed allylic alkylations of peptide amide enolates
Datta, Swarup,Kazmaier, Uli
, p. 872 - 880 (2011/04/16)
Pd-catalyzed allylations are an excellent tool for stereoselective peptide modifications, being clearly superior to normal alkylations. The reactions proceed not only in high yield, but also high regio- and diastereoselectivities, and trans-products are f
