Check Digit Verification of cas no

The CAS Registry Mumber 1154050-04-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,4,0,5 and 0 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1154050-04:
(9*1)+(8*1)+(7*5)+(6*4)+(5*0)+(4*5)+(3*0)+(2*0)+(1*4)=100
100 % 10 = 0
So 1154050-04-0 is a valid CAS Registry Number.

Catalytic, one-pot synthesis of β-amino acids from α-amino acids. Preparation of α,β-peptide derivatives

Saavedra, Carlos,Hernandez, Rosendo,Boto, Alicia,Alvarez, Eleuterio

supporting information; experimental part, p. 4655 - 4665 (2009/10/09)

(Chemical Equation Presented) The one-pot conversion of readily available α-amino acid into β-amino acid derivatives was carried out in good yields. The method is a sequential process initiated by a tandem radical decarboxylation-oxidation reaction; the resulting acyliminium ion was trapped by silyl ketenes. Stoichiometric and catalytic versions of this reaction were developed and then applied to prepare modified di- and tripeptides. Interestingly, some tripeptides formed expanded β-turns in the solid state.
