1340541-90-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1340541-90-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,0,5,4 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1340541-90:
(9*1)+(8*3)+(7*4)+(6*0)+(5*5)+(4*4)+(3*1)+(2*9)+(1*0)=123
123 % 10 = 3
So 1340541-90-3 is a valid CAS Registry Number.

A combined experimental-theoretical study on the lithiation/electrophilic quench reaction of benzylic position of (η5- tetramethylcyclohexadienyl)-Mn(CO)3

Rose, Eric,Dubarle-Offner, Julien,Rose-Munch, Francoise,Gerard, Helene

, p. 2375 - 2381 (2011/11/12)

An [(η6-1,2,4,5-tetramethylbenzene)Mn(CO)3] + BF4- complex treated with hydride gives a neutral (η5-1,2,4,5-tetramethylcyclohexadienyl)Mn(CO)3 complex whose X-ray analysis is described. Functionalization of the latter complex at a "benzylic" position using a lithiation/electrophilic quench sequence affords two regioisomers of which the major one corresponds to the functionalization at the C9 carbon. Theoretical computations show that the regioselectivity of lithiation is governed by the stability of the carbanion and thus by its conjugation.
