1019840-64-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1019840-64-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,9,8,4 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1019840-64:
(9*1)+(8*0)+(7*1)+(6*9)+(5*8)+(4*4)+(3*0)+(2*6)+(1*4)=142
142 % 10 = 2
So 1019840-64-2 is a valid CAS Registry Number.

Asymmetric Ni-catalyzed conjugate allylation of activated enones
Sieber, Joshua D.,Morken, James P.
, p. 4978 - 4983 (2008/09/20)
The nickel-catalyzed enantioselective addition of allylboronic acid pinacol ester, allylB(pin), is described. This reaction is highly effective with dialkylidene ketones and favors the allylation of the benzylidene site in nonsymmetric substrates. The rea
