80225-02-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 80225-02-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,2,2 and 5 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 80225-02:
(7*8)+(6*0)+(5*2)+(4*2)+(3*5)+(2*0)+(1*2)=91
91 % 10 = 1
So 80225-02-1 is a valid CAS Registry Number.

A Mild and convenient synthesis of 4-tosyl-4,5-dihydrooxazoles

Companyo, Xavier,Moyano, Albert,Rios, Ramon

experimental part, p. 293 - 296 (2010/04/23)

A facile and mild synthesis of 4-tosyl-4,5-dihydrooxazoles is described. The reaction between tosyl methyl isocyanide (TosMIC) and cinnamic or aromatic aldehydes is catalyzed by triethylamine, affording trans-5-styryl- or 5-aryl-4-tosyl-4,5-dihydrooxazole

Synthesis of 2,5-Disubstituted Oxazoles from Aldehydes and N-(Tosylmethyl)imino Synthons. Application to the Synthesis of Pimprinine Analogues

Houwing, Hendrik A.,Wildeman, Jurjen,van Leusen, Albert M.

, p. 1133 - 1139 (2007/10/02)

A series of N-(tosylmethyl)imino compounds has been applied to a new base induced, one-operational synthesis of 2,5-disubstituted oxazoles from aromatic aldehydes.For substituent A of the imino compounds, which becomes the 2-substituent in the oxazoles, has been chosen methoxy, methyl and phenyl.The new method has been used also to synthesize seven pimprinine analogues, i.e., 5-(3-indolyl)oxazoles.
