732-21-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 732-21-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,3 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 732-21:
(5*7)+(4*3)+(3*2)+(2*2)+(1*1)=58
58 % 10 = 8
So 732-21-8 is a valid CAS Registry Number.

Mild and convenient one-pot synthesis of 1,3,4-oxadiazoles

Stabile, Paolo,Lamonica, Alessandro,Ribecai, Arianna,Castoldi, Damiano,Guercio, Giuseppe,Curcuruto, Ornella

supporting information; experimental part, p. 4801 - 4805 (2010/10/02)

A mild, general, convenient, and efficient one-pot synthesis of 2-phenyl-5-substituted-1,3,4-oxadiazoles is described. Both (hetero)aryl and alkyl carboxylic acids were efficiently condensed with benzohydrazide in the presence of TBTU to give diacylhydrazine intermediates. The latter underwent a smooth TsCl-mediated cyclodehydration reaction to afford 2-phenyl-5-substituted- 1,3,4-oxadiazoles in good to very good yields.

Hypervalent iodine oxidation of acid hydrazides: A new synthesis of N,N'-diacylhydrazines

Prakash, Om,Sharma, Vijay,Sadana, Anil

, p. 3371 - 3377 (2007/10/03)

Hypervalent iodine oxidation of p-substituted benzohydrazides (1a-h), phenylacetohydrazide (1i) and heterocyclic acid hydrazides (1j-l) using one equivalent of iodobenzene diacetate in dry dichloromethane or acetonitrile leads to dimerization thereby providing a new and facile method for the synthesis of N,N-diacylhydrazines 2.
