Check Digit Verification of cas no

The CAS Registry Mumber 203914-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,9,1 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 203914-40:
(8*2)+(7*0)+(6*3)+(5*9)+(4*1)+(3*4)+(2*4)+(1*0)=103
103 % 10 = 3
So 203914-40-3 is a valid CAS Registry Number.

Tricarbonyl[(1-4-η)-2-methoxy-5-methylenecyclohexa-1,3-diene]iron as a synthetic intermediate: Sequential electrophilic and nucleophilic additions

Ong, Chi Wi,Wang, Junn Nan,Chien, Ting Ling

, p. 1442 - 1445 (1998)

Tricarbonyl[(1-4-η)-2-methoxy-5-methylene-cyclohexa-1,3-diene]iron reacts with electrophiles to give the cyclohexadienylium-Fe(CO)3 cation, which either reacts with nucleophiles to form a new quaternary center or undergoes competitive loss of an acidic α-proton to give a new triene complex. This constitutes a new reaction sequence for the synthesis of 4,4-disubstituted cyclohexen-2-ones with the simultaneous introduction of two functional groups.
