851398-45-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 851398-45-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,1,3,9 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 851398-45:
(8*8)+(7*5)+(6*1)+(5*3)+(4*9)+(3*8)+(2*4)+(1*5)=193
193 % 10 = 3
So 851398-45-3 is a valid CAS Registry Number.

Synthesis of 3,5-diaryl-4-(1H-imidazol- 2-yl)-1H-pyrazoles from 2-phenacyl- 1H-imidazole
Dzvinchuk,Nesterenko,Lozinskii
experimental part, p. 66 - 71 (2010/08/19)
A method of synthesis is proposed for previously unknown 3,5-diaryl-4-(1H-imidazol-2-yl)-1H-pyra-zoles based on the thermal intramolecular cyclocondensation of aroylhydrazones of 2-phenacyl-1H-imidazole.
