Check Digit Verification of cas no
The CAS Registry Mumber 5334-56-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,3 and 4 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5334-56:
(6*5)+(5*3)+(4*3)+(3*4)+(2*5)+(1*6)=85
85 % 10 = 5
So 5334-56-5 is a valid CAS Registry Number.

Aryl Coupling Reactions of Pyrazolopyrimidin-4-yl Radicals

4-Arylpyrazolopyrimidines (4) were the subjects of a synthetic investigation in order to evaluate their biological activity.Attempts to prepare 4 from 4-aminopyrazolopyrimidines (5) via classical Gomberg-Bachmann-Hey aryl coupling conditions failed.Conversion of 5 to 4 was accomplished by diazotiazation of 5 using alkyl nitrites with an acid catalyst in aromatic solvents.Isomer distribution of the aryl-coupled products 4 was that predicted for a radical intermediate (ortho > meta ca. para); isomer structures were assigned by a detailed 1H NMR analysis.Unusual fragmentation products 17 and 18 were isolated during the course of investigations.These oxadiazoles probably arise from collapse of intermediate pyrazolopyrimidin-4-yl radicals 15.
