2425-93-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2425-93-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,2 and 5 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2425-93:
(6*2)+(5*4)+(4*2)+(3*5)+(2*9)+(1*3)=76
76 % 10 = 6
So 2425-93-6 is a valid CAS Registry Number.

The Synthesis Of (1,3,4-Oxadiazole-2,5-Diyl) Dibenzoic Acids and Their Thiadiazole Analogues
Javaid, Khalid,Smith, David M.
, p. 985 - 997 (2007/10/02)
The title compounds are best prepared by oxidation of the corresponding 2,5-ditolyl-1,3-4-oxadiazole or -thiadiazole, and are most easily characterised by the 13C n.m.r. spectra of their di-potassium salts.
