80049-16-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80049-16-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,0,4 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 80049-16:
(7*8)+(6*0)+(5*0)+(4*4)+(3*9)+(2*1)+(1*6)=107
107 % 10 = 7
So 80049-16-7 is a valid CAS Registry Number.

Reaction of Maleimides and Ethyl 3-Aminocrotonates. A Reinvestigation Leading to an Improved Synthesis of Pyrrolopyridines
Shah, Kanhaiya R.,Blanton, C. DeWitt
, p. 502 - 508 (2007/10/02)
Conditions employed for the reaction between maleimides and ethyl aminocrotonates were shown to yield pyrrolopyridines rather than the previously reported pyrrolopyrroles.
