Check Digit Verification of cas no
The CAS Registry Mumber 143209-28-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,2,0 and 9 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 143209-28:
(8*1)+(7*4)+(6*3)+(5*2)+(4*0)+(3*9)+(2*2)+(1*8)=103
103 % 10 = 3
So 143209-28-3 is a valid CAS Registry Number.

SYNTHESIS of 1,2,4-TRIAZINES - XIV. Regioselective Synthesis of Ethyl 1,2,4-Triazine-5-carboxylates
Ohsumi, Tadashi,Neunhoeffer, Hans
, p. 5227 - 5234 (2007/10/02)
Ethyl 1,2,4-triazine-5-carboxylates 6 were prepared by heating N,N-dimethylaminomethylene- or ethoxymethylenehydrazones 5 with ammonium acetate in acetic acid at 100 deg C.NMR studies confirmed the absence of their regio isomers (6-carboxylates), showing
