227774-72-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 227774-72-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,7,7,7 and 4 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 227774-72:
(8*2)+(7*2)+(6*7)+(5*7)+(4*7)+(3*4)+(2*7)+(1*2)=163
163 % 10 = 3
So 227774-72-3 is a valid CAS Registry Number.

Asymmetric functionalisation of tricarbonylchromium(0) complexes of arenes by non-racemic chiral bases

Gibson, Susan E.,Reddington, Ellian G.

, p. 989 - 996 (2007/10/03)

Non-racemic chiral bases have been proven to be of significant use in the synthesis of a wide range of enantiomerically enriched organic molecules. Their use in the synthesis of organometallic reagents and catalysts, however, is still in its infancy. This article reviews one of the first areas of organometallic chemistry to be examined in this context, i.e. asymmetric functionalisation of tricarbonylchromium(0) complexes of arenes using non- racemic chiral bases.
