Check Digit Verification of cas no

The CAS Registry Mumber 50778-60-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,7,7 and 8 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 50778-60:
(7*5)+(6*0)+(5*7)+(4*7)+(3*8)+(2*6)+(1*0)=134
134 % 10 = 4
So 50778-60-4 is a valid CAS Registry Number.

Syntheses and characterization of 2-amino-5-aryl-1,3,4-oxadiazoles containing trifluoroethoxy groups

Zhang, Rong,Qian, Xuhong,Li, Zhong

, p. 39 - 43 (2007/10/03)

In order to develop an effective synthetic route to 2-amino-5-aryl-1,3,4-oxadiazoles containing trifluoroethoxy groups, a novel intermediate 2-amino-5-[4-(2′,2′,2′-trifluoroethoxy)-phenyl]-1,3,4- oxadiazole was prepared and its structure was confirmed by

Polyfluoroalkoxy-substituted aromatic carboxylic amides and hydrozides

-

, (2008/06/13)

Acyl halides, esters, amides, hydrazides and salts as well as the acid form derived from aromatic acids substituted by polyfluoroalkoxy groups. These compounds are valuable as synthetic intermediates in the preparation of physiologically active compounds.
