Check Digit Verification of cas no

The CAS Registry Mumber 90001-53-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,0,0 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 90001-53:
(7*9)+(6*0)+(5*0)+(4*0)+(3*1)+(2*5)+(1*3)=79
79 % 10 = 9
So 90001-53-9 is a valid CAS Registry Number.

Synthesis of 1,3,4-Oxadiazoles via Annulation of Hydrazides and Benzene-1,3,5-triyl Triformate under Metal-Free Conditions

Yin, Zhiping,Power, Dennis J.,Wang, Zechao,Stewart, Scott G.,Wu, Xiao-Feng

A new and efficient method for the synthesis of 1,3,4-oxadiazoles via the annulation of hydrazides with benzene-1,3,5-triyl triformate (TFBen) under metal-free conditions is reported. A broad range of hydrazides were transformed into the corresponding 1,3

Efficient synthesis of 1,3,4-oxadiazoles promoted by NH4Cl

Gnanasekaran, Krishna Kumar,Nammalwar, Baskar,Murie, Maeghan,Bunce, Richard A.

supporting information, p. 6776 - 6778 (2015/01/09)

An efficient and inexpensive approach to the synthesis of 2-substituted and 2,5-disubstituted 1,3,4-oxadiazoles from arylhydrazides and orthoesters is reported using catalytic NH4Cl. The conditions are mild, and thus, compatible with a variety of functional groups. The optimized reaction is performed using 30 mol % of NH4Cl in 100% EtOH and is generally complete within 1 h for non-aromatic orthoesters and 2-10 h for aromatic orthoesters. The reaction permits both electron-releasing and electron-withdrawing groups on the arylhydrazide substrate. Most products are formed in high yields and require only minimal purification. Compared with earlier reports, the current reactions proceed in shorter time and require less of the orthoester.
