Check Digit Verification of cas no

The CAS Registry Mumber 320740-34-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,0,7,4 and 0 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 320740-34:
(8*3)+(7*2)+(6*0)+(5*7)+(4*4)+(3*0)+(2*3)+(1*4)=99
99 % 10 = 9
So 320740-34-9 is a valid CAS Registry Number.

The synthesis of C2-symmetric and axially chiral compounds for recognition and catalysis

Clews, John,Curtis, Anthony D.M.,Malkin, Hugh

, p. 8735 - 8746 (2007/10/03)

Axially chiral amidines and guanidines, some possessing C2-symmetry, have been targeted as potential chiral catalysts for reactions of α,β-unsaturated carboxylic acids or esters. The key step in each synthesis required the coupling of two sterically demanding aromatic compounds to form atropisomeric biaryl species. (C) 2000 Elsevier Science Ltd.
