139874-44-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139874-44-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,8,7 and 4 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 139874-44:
(8*1)+(7*3)+(6*9)+(5*8)+(4*7)+(3*4)+(2*4)+(1*4)=175
175 % 10 = 5
So 139874-44-5 is a valid CAS Registry Number.

Synthesis of visoltricin and fungerin: Imidazole derivatives of Fusarium sp.
Rieder, Johann M.,Lepschy, Johann
, p. 2375 - 2376 (2007/10/03)
The synthesis of two imidazole derivatives of Fusarium sp. is described. 3-[1-Methyl-4-(3-methyl-2-butenyl)-1H-imidazol-5-yl]-2(E)-propenoic acid methylester was synthesized for the first time and spectroscopic data showed differences to the reported data
