244248-72-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 244248-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,4,2,4 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 244248-72:
(8*2)+(7*4)+(6*4)+(5*2)+(4*4)+(3*8)+(2*7)+(1*2)=134
134 % 10 = 4
So 244248-72-4 is a valid CAS Registry Number.

Synthesis of 2,3,4,6-tetrasubstituted pyridines as precursors to bicycles and polycycles
Abu-Shanab, Fathi A.
, p. 430 - 431 (2007/10/03)
Ammonium 1,1,3-tricyano-2-methylprop-2-enide 1a and sodium 2-amino-1,1,3-tricyanoprop-2-enide 1b are treated with H2S in absolute ethanol to afford 3,4,6-trisubstituted pyridine-2(1H)-thione 3a,b; their structures are confirmed by reaction with
