Check Digit Verification of cas no

The CAS Registry Mumber 1400576-22-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,0,5,7 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1400576-22:
(9*1)+(8*4)+(7*0)+(6*0)+(5*5)+(4*7)+(3*6)+(2*2)+(1*2)=118
118 % 10 = 8
So 1400576-22-8 is a valid CAS Registry Number.

Highly selective synthesis of tetra-substituted furans and cyclopropenes: Copper(i)-catalyzed formal cycloadditions of internal aryl alkynes and diazoacetates

Swenson, Andrew K.,Higgins, Kate E.,Brewer, Matthew G.,Brennessel, William W.,Coleman, Michael G.

, p. 7483 - 7486 (2012/10/30)

A convenient Cu(i)-catalyzed cycloaddition of electron rich internal aryl alkynes and diazoacetates was discovered for the chemoselective and regioselective synthesis of tetra-substituted furans and cyclopropenes in moderate isolated yields (18-67%), and alkyne conversion (29-73%).
