340983-06-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 340983-06-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,0,9,8 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 340983-06:
(8*3)+(7*4)+(6*0)+(5*9)+(4*8)+(3*3)+(2*0)+(1*6)=144
144 % 10 = 4
So 340983-06-4 is a valid CAS Registry Number.

Synthetic studies toward diazonamide A. A novel approach for polyoxazole synthesis
Wipf, Peter,Methot, Joey-Lee
, p. 1261 - 1263 (2007/10/03)
(equation presented) The indole-bisoxazole fragment of diazonamide A was prepared by a Chan-type rearrangement of a tertiary amide. This approach represents a remarkably direct strategy for polyoxazole synthesis.
