Check Digit Verification of cas no

The CAS Registry Mumber 53720-72-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,7,2 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 53720-72:
(7*5)+(6*3)+(5*7)+(4*2)+(3*0)+(2*7)+(1*2)=112
112 % 10 = 2
So 53720-72-2 is a valid CAS Registry Number.

An [(NHC)(NHCEWG)RuCl2(CHPh)] complex for the efficient formation of sterically hindered olefins by ring-closing metathesis

Vorfait, Tim,Leuthaeusser, Steffen,Plenio, Herbert

supporting information; experimental part, p. 5191 - 5194 (2009/12/24)

NHC with EWGs for RCM: Ruthenium complexes with two N-heterocyclic carbenes (NHCs), one of them substituted with electron-withdrawing groups (EWGs), are highly efficient (pre) catalysts for the synthesis of tetrasubstituted olefins and trisubstituted olef

PRODUCTION OF 2,5-DIHYDROFURANS AND ANALOGOUS COMPOUNDS

Page/Page column 8, (2008/06/13)

Vinyl oxiranes are rearranged to 2,5-dihydrofuran using catalyst (III) or (IV). The 2,5-dihydrofuran can be reduced to tetrahydrofuran. 3,4-Epoxy-l-butene substrate is converted to 2,5-dihydrofuran which in turn is converted to tetrahydrofuran. Substrate
