284021-86-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 284021-86-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,4,0,2 and 1 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 284021-86:
(8*2)+(7*8)+(6*4)+(5*0)+(4*2)+(3*1)+(2*8)+(1*6)=129
129 % 10 = 9
So 284021-86-9 is a valid CAS Registry Number.

Copper hydride-catalyzed tandem 1,4-reduction/alkylation reactions

Lipshutz, Bruce H.,Chrisman, Will,Noson, Kevin,Papa, Patrick,Sclafani, Joseph A.,Vivian, Randall W.,Keith, John M.

, p. 2779 - 2788 (2000)

Exposure of an enone to a catalytic quantity of [CuH(PPh3)]6 in the presence of one of several silyl hydrides (PhMe2SiH, PMHS, HMe2SiOSiMe2H) leads to conjugate reduction with concomitant formation of the corresponding silyl enol ether. Without isolation, treatment of these intermediates with a Lewis acid at low temperatures in the presence of an aldehyde, or with fluoride ion together with an activated halide, affords good yields of the product of 3-component coupling (3-CC) in a single reaction flask.
