Check Digit Verification of cas no

The CAS Registry Mumber 221230-39-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,2,3 and 0 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 221230-39:
(8*2)+(7*2)+(6*1)+(5*2)+(4*3)+(3*0)+(2*3)+(1*9)=73
73 % 10 = 3
So 221230-39-3 is a valid CAS Registry Number.

New cascade processes on group 6 fischer-type carbene complexes: Cyclopropanation and metathesis reactions

Barluenga, Jose,Andina, Facundo,Aznar, Fernando,Valde, Carlos

, p. 4143 - 4146 (2008/02/12)

Alkynyl Fischer carbone complexes 1, which feature a pendant olefin group, undergo novel cascade processes triggered by [2+2], [3+2], and [4+2] cycloadditions. Competition between cyclopropanation and olefin metathesis is controlled by the substitution at
