Check Digit Verification of cas no

The CAS Registry Mumber 15568-77-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,5,6 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 15568-77:
(7*1)+(6*5)+(5*5)+(4*6)+(3*8)+(2*7)+(1*7)=131
131 % 10 = 1
So 15568-77-1 is a valid CAS Registry Number.

Dioxazoles, a new mild nitrene transfer reagent in gold catalysis: Highly efficient synthesis of functionalized oxazoles

Chen, Ming,Sun, Ning,Chen, Haoyi,Liu, Yuanhong

, p. 6324 - 6327 (2016/05/19)

A gold-catalyzed regioselective [3+2] cycloaddition of ynamides with 1,4,2-dioxazoles was developed and offers a novel approach to obtain highly functionalized oxazoles under mild reaction conditions. 1,4,2-Dioxazole was found to act as an efficient N-acyl nitrene equivalent to trigger a facile generation of α-imino gold-carbene intermediate through the elimination of a ketone.
