219851-78-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 219851-78-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,8,5 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 219851-78:
(8*2)+(7*1)+(6*9)+(5*8)+(4*5)+(3*1)+(2*7)+(1*8)=162
162 % 10 = 2
So 219851-78-2 is a valid CAS Registry Number.

High yielding synthesis of dehydroamino acid and dehydropeptide derivatives
Ferreira, Paula M.T.,Maia, Hernani L.S.,Monteiro, Luis S.,Sacramento, Joana
, p. 3697 - 3703 (1999)
By using a 4-dimethylaminopyridine (DMAP) catalysed reaction of β-hydroxyamino acid derivatives with tert-butyl pyrocarbonate [(Boc)2O], dehydroamino acid derivatives are obtained in high yields. The same methodology applied to dipeptides with
