128600-19-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128600-19-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,6,0 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128600-19:
(8*1)+(7*2)+(6*8)+(5*6)+(4*0)+(3*0)+(2*1)+(1*9)=111
111 % 10 = 1
So 128600-19-1 is a valid CAS Registry Number.

Nitrile Additions to C,N-Diacylimines. Formation of 4-Amidooxazoles
Fischer, Bilha,Hassner, Alfred
, p. 5225 - 5229 (2007/10/02)
Nitriles are shown to react with C,N-diacylimines 2, generated in situ from 1 or 4 in the presence of Lewis acids, to produce 4-amidooxazoles 5 and 6 in good to excellent yield.Diamides are sometimes also produced.The reaction was followed by NMR spectros
