Check Digit Verification of cas no

The CAS Registry Mumber 289909-73-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,9,0 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 289909-73:
(8*2)+(7*8)+(6*9)+(5*9)+(4*0)+(3*9)+(2*7)+(1*3)=215
215 % 10 = 5
So 289909-73-5 is a valid CAS Registry Number.

Neutral macrocycles via halide-induced ring opening of binuclear condensed intermediates

Dixon, Felicia M.,Eisenberg, Adam H.,Farrell, Joshua R.,Mirkin, Chad A.,Liable-Sands, Louise M.,Rheingold, Arnold L.

, p. 3431 - 3433 (2008/10/08)

A novel halide-assisted approach for opening Rh(I)-thioether-based condensed intermediates into binuclear macrocycles is reported. This novel ring-opening reaction provides entry into a class of neutral binuclear macrocycles prepared via the 'weak-link' synthetic strategy.
