94243-20-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 94243-20-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,2,4 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 94243-20:
(7*9)+(6*4)+(5*2)+(4*4)+(3*3)+(2*2)+(1*0)=126
126 % 10 = 6
So 94243-20-6 is a valid CAS Registry Number.

Reinvestigation of the reaction of 3-substituted 1,2,4-triazines with nitronate anions: unexpected behavior of 3-(2-ethoxyphenyl)-1,2,4-triazine in the reaction with anions of nitroalkanes

Mojzych, Mariusz,Bernat, Zofia,Karczmarzyk, Zbigniew

, p. 968 - 977 (2019)

[Figure not available: see fulltext.] 3-Substituted 1,2,4-triazines easily react with nitronate anions to replace hydrogen atom in the position C-5 according to nucleophilic substitution mechanism and form appropriate oximes of 5-formyl- or 5-acyl-1,2,4-t

Enantioselective reduction of 5-acyl-1,2,4-triazines and their oximes by baker's yeast [1]

Rykowski,Lipinska,Guzik,Adamiuk,Olender

, p. 69 - 76 (2007/10/03)

Variously substituted 5-acyl-1,2,4-triazines 4a-d were regioselectively synthesized through a sequence involving nucleophilic acylation of 1,2,4-triazines 1a-b with nitronate anions 2a-c followed by hydrolysis of the oximes 3a-d thus formed, by sodium hyd
