Check Digit Verification of cas no

The CAS Registry Mumber 1621167-84-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,1,1,6 and 7 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1621167-84:
(9*1)+(8*6)+(7*2)+(6*1)+(5*1)+(4*6)+(3*7)+(2*8)+(1*4)=147
147 % 10 = 7
So 1621167-84-7 is a valid CAS Registry Number.

Catalytic C-H activation of arylacetylenes: A fast assembly of 3-(arylethynyl)-3-hydroxyindolin-2-ones using CuI/DBU

Chouhan, Mangilal,Senwar, Kishna Ram,Kumar, Kapil,Sharma, Ratnesh,Nair, Vipin A.

, p. 195 - 202 (2014/03/21)

A highly efficient and atom-economic methodology has been developed for the synthesis of 3-(arylethynyl)-3-hydroxyindolin-2-ones from isatins by C-H activation of arylacetylenes using a catalytic quantity of copper(I) iodide (5 mol%) and DBU (20 mol%) at 25°C, affording the products in excellent yields in very short reaction time (5 min).
