100449-31-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 100449-31-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,4,4 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 100449-31:
(8*1)+(7*0)+(6*0)+(5*4)+(4*4)+(3*9)+(2*3)+(1*1)=78
78 % 10 = 8
So 100449-31-8 is a valid CAS Registry Number.

Himbert, Gerhard,Brunn, Wolfgang
, p. 1067 - 1073 (2007/10/02)
The ynamines 1 react with the 2-oxo-2H-pyrancarboxylates 2-4 by regiospecific cycloaddition.After spontaneous extrusion of carbon dioxide the aminobenzoic acid derivatives 6-8 are isolated.
