Check Digit Verification of cas no

The CAS Registry Mumber 1907-97-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,0 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1907-97:
(6*1)+(5*9)+(4*0)+(3*7)+(2*9)+(1*7)=97
97 % 10 = 7
So 1907-97-7 is a valid CAS Registry Number.

Tin(IV) triflimidate-catalyzed cyclization of epoxy esters to functionalized δ-hydroxy-γ-lactones

Antoniotti, Sylvain,Du?ach, Elisabet

scheme or table, p. 2536 - 2539 (2009/07/26)

In the presence of 5 mol % of tin(IV) triflimidate, a cyclization reaction of epoxyesters to δ-hydroxy-γ-lactones proceeding in 46-98% yields without additives, ligands, or co-catalysts was observed. The cyclization to five-membered rings is greatly favor
