Check Digit Verification of cas no

The CAS Registry Mumber 634-19-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,3 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 634-19:
(5*6)+(4*3)+(3*4)+(2*1)+(1*9)=65
65 % 10 = 5
So 634-19-5 is a valid CAS Registry Number.

Intramolecular Vinylation of Aryl Rings by Vinyl Cations

Fang, Jian,Brewer, Matthias

supporting information, p. 7384 - 7387 (2019/01/03)

A Lewis acid mediated intramolecular electrophilic vinylation of aryl rings by vinyl cations is reported. This reaction takes advantage of β-hydroxy-α-diazo ketones as vinyl cation precursors and provides good yields of tricyclic 1-indenones that contain
