Check Digit Verification of cas no

The CAS Registry Mumber 1214922-06-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,4,9,2 and 2 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1214922-06:
(9*1)+(8*2)+(7*1)+(6*4)+(5*9)+(4*2)+(3*2)+(2*0)+(1*6)=121
121 % 10 = 1
So 1214922-06-1 is a valid CAS Registry Number.

Single-Step Synthesis of Iodinated Oxazoles from N-Propargyl Amides Mediated by I2/Iodosylbenzene/Trimethylsilyl Trifluoromethanesulfonate Systems

Suzuki, Sho,Saito, Akio

, p. 11859 - 11864 (2017)

A combination of I2, iodosylbenzene, and trimethylsilyl trifluoromethanesulfonate (TMSOTf) is effective for single-step synthesis of iodinated oxazoles from N-propargyl amides via the aromatization of the iodocyclized intermediates, which has difficulty proceeding through conventional iodocyclization methods. Compared to the former method consisting of the metal-catalyzed cyclization of N-propargyl amides followed by halogenation of alkylideneoxazolines, the present reaction provides a facile and metal-free procedure.
