Check Digit Verification of cas no

The CAS Registry Mumber 32781-23-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,7,8 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 32781-23:
(7*3)+(6*2)+(5*7)+(4*8)+(3*1)+(2*2)+(1*3)=110
110 % 10 = 0
So 32781-23-0 is a valid CAS Registry Number.

Mechanosynthesis of Odd-Numbered Tetraaryl[n]cumulenes

Ardila-Fierro, Karen J.,Bolm, Carsten,Hernández, José G.

supporting information, p. 12945 - 12949 (2019/08/01)

A mechanochemical synthesis of one-dimensional carbon allotrope carbyne model compounds, namely tetraaryl[n]cumulenes (n=3, 5) was realized. Central for the mechanosynthesis of the cumulenic carbon nanostructures were the development of a mechanochemical Favorskii alkynylation-type reaction and the implementation of a solvent-free, acid-free reductive elimination with tin(II) chloride by ball milling.
