Check Digit Verification of cas no

The CAS Registry Mumber 1222181-40-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,2,1,8 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1222181-40:
(9*1)+(8*2)+(7*2)+(6*2)+(5*1)+(4*8)+(3*1)+(2*4)+(1*0)=99
99 % 10 = 9
So 1222181-40-9 is a valid CAS Registry Number.

supporting information; experimental part, p. 3484 - 3487 (2010/08/05)

A selective protocol for the synthesis of 2-methylene-3-substituted-2,3- dihydro-1H-inden-1-ones and 2-benzylidene-2,3-dihydro-1H-inden-1-ones has been developed via palladium-catalyzed cyclocarbonylation reactions of arynes with allyl carbonates and carbon monooxide (CO). It is noteworthy that the selectivity of this new route is depended on both substrates and ligands.
