654069-56-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 654069-56-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,4,0,6 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 654069-56:
(8*6)+(7*5)+(6*4)+(5*0)+(4*6)+(3*9)+(2*5)+(1*6)=174
174 % 10 = 4
So 654069-56-4 is a valid CAS Registry Number.

Aromatic nucleophilic substitution in 1,2,4-triazine 4-oxides with Grignard reagents
Prokhorov,Kozhevnikov,Rusinov,Chupakhin
, p. 1157 - 1161 (2007/10/03)
Addition of the Grignard reagents to 1,2,4-triazine 4-oxides followed by aromatization of the intermediate σH-adducts by dehydrogenation or dehydration was used for synthesis of 5-alkyl- or 5-aryl-substituted 1,2,4-triazines and their 4-oxides.
