112142-72-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 112142-72-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,1,4 and 2 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 112142-72:
(8*1)+(7*1)+(6*2)+(5*1)+(4*4)+(3*2)+(2*7)+(1*2)=70
70 % 10 = 0
So 112142-72-0 is a valid CAS Registry Number.

Selective Amide Cleavage in Peptides Containing α,α-Disubstituted α-Amino Acids
Wipf, Peter,Heimgartner, Heinz
, p. 354 - 368 (1987)
A new synthesis of dipeptides with terminal α,α-disubstituted α-amino acids, using 2,2-disubstituted 3-amino-2H-azirines 1 as amino-acid equivalents, is demonstrated.The reaction of 1 with N-protected amino acids leads to the corresponding dipeptide amide
