91913-84-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91913-84-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,9,1 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 91913-84:
(7*9)+(6*1)+(5*9)+(4*1)+(3*3)+(2*8)+(1*4)=147
147 % 10 = 7
So 91913-84-7 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.
