113447-04-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113447-04-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,4,4 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 113447-04:
(8*1)+(7*1)+(6*3)+(5*4)+(4*4)+(3*7)+(2*0)+(1*4)=94
94 % 10 = 4
So 113447-04-4 is a valid CAS Registry Number.

A Convenient Synthesis of 2-Substituted 4-Amino-5-pyrimidinecarbonitriles
Schmidt, Hans-Werner,Koitz, Gerald,Junek, Hans
, p. 1305 - 1307 (2007/10/02)
Synthesis of the novel 2-halogenated 4-amino-5-pyrimidinecarbonitriles 3a,b starting from ethoxymethylenemalononitrile 1 and cyanamide is described.Nucleophilic substitution of the reactive halogen atom leads to the derivatives 5a-g,6 and 7a-h.
