Check Digit Verification of cas no

The CAS Registry Mumber 30238-20-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,2,3 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 30238-20:
(7*3)+(6*0)+(5*2)+(4*3)+(3*8)+(2*2)+(1*0)=71
71 % 10 = 1
So 30238-20-1 is a valid CAS Registry Number.

Ruthenium-catalyzed [2 + 2] cycloadditions of bicyclic alkenes with alkynyl phosphonates

Cockburn, Neil,Karimi, Elham,Tam, William

supporting information; experimental part, p. 5762 - 5765 (2009/12/08)

(Chemical Equation Presented) Ruthenium-catalyzed [2 + 2] cycloadditions of bicyclic alkenes with alkynyl phosphonates were investigated. The phosphonate moieties were found to be compatible with the Ru-catalyzed cycloadditions giving the corresponding cy
