14500-25-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 14500-25-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,5,0 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 14500-25:
(7*1)+(6*4)+(5*5)+(4*0)+(3*0)+(2*2)+(1*5)=65
65 % 10 = 5
So 14500-25-5 is a valid CAS Registry Number.

A REINVESTIGATION OF THE REACTIONS BETWEEN DIAZOMETHANE AND 1-PHENYLURAZOLE
Bausch, M. J.,Wang, L.-H.
, p. 601 - 608 (2007/10/02)
Exhaustive methylation of 1-phenylurazole (1), using ethereal diazomethane as the methylating agent, results in the formation of three products: 1-phenyl-3,5-dimethoxy-1,2,4-triazole (2), 1-phenyl-3-methoxy-4-methyl-Δ2-1,2,4-triazoline-5-one (3
