Check Digit Verification of cas no

The CAS Registry Mumber 545358-08-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,5,3,5 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 545358-08:
(8*5)+(7*4)+(6*5)+(5*3)+(4*5)+(3*8)+(2*0)+(1*8)=165
165 % 10 = 5
So 545358-08-5 is a valid CAS Registry Number.

Novel chiral dibenzo[a,c]cycloheptadiene bis(oxazoline) and catalytic enantioselective cyclopropanation of styrene

Du, Da-Ming,Fu, Bin,Hua, Wen-Ting

, p. 1933 - 1938 (2003)

A series of chiral C2-symmetric bis(oxazoline) ligands containing dibenzo[a,c]cycloheptadiene units were synthesized. The copper complexes, prepared in situ from copper (I)-triflate and the new enantiopure oxazoline ligands, were assessed as chiral catalysts in the enantioselective cyclopropanation of styrene with diazoacetate. Enantioselectivities up to 82 and 62%, respectively, for trans- and cis-2-phenylcyclopropanecarboxylate were observed.
