Check Digit Verification of cas no

The CAS Registry Mumber 20440-21-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,4 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 20440-21:
(7*2)+(6*0)+(5*4)+(4*4)+(3*0)+(2*2)+(1*1)=55
55 % 10 = 5
So 20440-21-5 is a valid CAS Registry Number.

Inside-outside stereoisomerism. 5. Synthesis and reactivity of trans-bicyclo[n.3.1]alkanones prepared via the intramolecular photocycloaddition of dioxenones

Winkler, Jeffrey D.,Hong, Bor-Cherng,Hey, John P.,Williard, Paul G.

, p. 8839 - 8846 (2007/10/02)

The stereoselectivity of the intramolecular photocycloaddition of a series of bicyclic dioxenones has been examined. The selective formation of trans-fused photoadducts is observed in almost all cases, which upon fragmentation lead to the synthesis of bic
