Check Digit Verification of cas no
The CAS Registry Mumber 20771-08-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,7,7 and 1 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 20771-08:
(7*2)+(6*0)+(5*7)+(4*7)+(3*1)+(2*0)+(1*8)=88
88 % 10 = 8
So 20771-08-8 is a valid CAS Registry Number.

O-Transfer-facilitated cyclizations of propargylamides with TMSN3: Selective synthesis of tetrazoles and dihydroimidazoles

An unprecedented formal [3+2] annulation of propargylamides with TMSN3 to deliver functionalized tetrazoles is developed. Oxygen-atom transfer (OAT) from the amide group to the CC bond was realized via a NIS-triggered-cyclization/ring-opening cascade pathway. The OAT process enables the amide to serve as a two-atom unit in the reactions. Notably, in situ umpolung of azide occurred when terminal propargylamides were employed in this reaction, providing an array of diiodomethylated dihydroimidazoles.
A flexible synthetic approach to the hennoxazoles

, p. 623 - 627 (2007/10/03)
Three advanced intermediates corresponding to the carbon skeleton of the hennoxazoles have been prepared. Central to the strategy is the synthesis of the oxazoles prior to coupling with the other fragments and a dithiane addition to allow for the generati
