545369-35-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 545369-35-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,5,3,6 and 9 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 545369-35:
(8*5)+(7*4)+(6*5)+(5*3)+(4*6)+(3*9)+(2*3)+(1*5)=175
175 % 10 = 5
So 545369-35-5 is a valid CAS Registry Number.

Synthesis and reactions of 1,2,3-triazinium salts
Ma?ttner, Michael,Neunhoeffer, Hans
, p. 413 - 425 (2007/10/03)
The synthesis of monosubstituted 1,2,3-triazinium salts 7-9 and their reactivity towards C-nucleophiles is described. The nucleophilic attack at 7-9 is regioselective at position 5, isolation of dihydroproducts was possible and an unusual ring contraction was observed.
