871798-84-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 871798-84-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,1,7,9 and 8 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 871798-84:
(8*8)+(7*7)+(6*1)+(5*7)+(4*9)+(3*8)+(2*8)+(1*4)=234
234 % 10 = 4
So 871798-84-4 is a valid CAS Registry Number.

Improved methodologies for the preparation of highly substituted pyridines
Sainz, Yolanda Fernandez,Raw, Steven A.,Taylor, Richard J. K.
, p. 10086 - 10095 (2007/10/03)
Two separate strategies have been developed for the preparation of highly substituted pyridines from 1,2,4-triazines via the inverse-electron-demand Diels-Alder reaction: a microwave-promoted, solvent-free procedure and a tethered imine-enamine (TIE) appr
