Check Digit Verification of cas no

The CAS Registry Mumber 1616562-83-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,6,5,6 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1616562-83:
(9*1)+(8*6)+(7*1)+(6*6)+(5*5)+(4*6)+(3*2)+(2*8)+(1*3)=174
174 % 10 = 4
So 1616562-83-4 is a valid CAS Registry Number.

Synthesis of α-Fluoroketones from Vinyl Azides and Mechanism Interrogation

Wu, Shu-Wei,Liu, Feng

, p. 3642 - 3645 (2016)

An efficient and mild fluorination of vinyl azides for the synthesis of α-fluoroketones is described. The mechanistic studies indicated that a single-electron transfer (SET) and a subsequent fluorine atom transfer process could be involved in the reaction.

General silver-catalyzed hydroazidation of terminal alkynes by combining TMS-N3 and H2O: Synthesis of vinyl azides

Liu, Zhenhua,Liao, Peiqiu,Bi, Xihe

supporting information, p. 3668 - 3671 (2014/08/05)

A general hydroazidation of unactivated alkynes using silver catalysis is reported. The reactions of diverse terminal alkynes with trimethylsilyl azide (TMS-N3) in the presence of H2O afforded the corresponding vinyl azides in good to excellent yields. This reaction has a broad substrate scope, good functional group tolerance, simple operation, and high reaction efficiency, thus providing an easy access to various functionalized vinyl azides.
