333350-50-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 333350-50-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,3,3,5 and 0 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 333350-50:
(8*3)+(7*3)+(6*3)+(5*3)+(4*5)+(3*0)+(2*5)+(1*0)=108
108 % 10 = 8
So 333350-50-8 is a valid CAS Registry Number.

A rapid synthesis of 2-aryl-5-substituted-2,3-dihydrobenzofurans

Kuethe, Jeffrey T.,Wong, Audrey,Journet, Michel,Davies, Ian W.

, p. 3727 - 3729 (2007/10/03)

(Chemical Equation Presented) An effective strategy has been developed for the rapid and efficient one-pot synthesis of 2-aryl-5-substituted-2,3- dihydrobenzofurans from readily available o-nitrotoluenes and aromatic aldehydes. This strategy allows access to a structurally diverse array of products for further manipulation.
