Check Digit Verification of cas no

The CAS Registry Mumber 1450606-99-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,0,6,0 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1450606-99:
(9*1)+(8*4)+(7*5)+(6*0)+(5*6)+(4*0)+(3*6)+(2*9)+(1*9)=151
151 % 10 = 1
So 1450606-99-1 is a valid CAS Registry Number.

Oxidize Amines to Nitrile Oxides: One Type of Amine Oxidation and Its Application to Directly Construct Isoxazoles and Isoxazolines

Zhang, Xiao-Wei,He, Xiao-Lin,Yan, Nan,Zheng, Hong-Xing,Hu, Xiang-Guo

, p. 15726 - 15735 (2020/11/30)

A facile oxidative heterocyclization of commercially available amines and tert-butyl nitrite with alkynes or alkenes leading to isoxazoles or isoxazolines is described. The unprecedented strategy of the oxidation of an amine directly to a nitrile oxide was used in this cyclization process. This reaction is highly efficient, regiospecific, operationally simple, mild, and tolerant of a variety of functional groups. Control experiments support a nitrile oxide intermediate mechanism for this novel class of oxidative cyclization reactions. Moreover, synthetic applications toward bioactive molecular skeletons and the late-stage modification of drugs were realized.
