277334-65-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 277334-65-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,7,3,3 and 4 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 277334-65:
(8*2)+(7*7)+(6*7)+(5*3)+(4*3)+(3*4)+(2*6)+(1*5)=163
163 % 10 = 3
So 277334-65-3 is a valid CAS Registry Number.

Modifications of peptides by chelate claisen rearrangements of manganese enolates
Maier, Sabine,Kazmaier, Uli
, p. 1241 - 1251 (2007/10/03)
Deprotonation of allylic esters of peptides at -70 °C in the presence of metal salts results in the formation of metal peptide enolate complexes, which undergo Claisen rearrangement on warming to room temperature to produce stereoselectively modified pept
