64504-73-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 64504-73-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,5,0 and 4 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 64504-73:
(7*6)+(6*4)+(5*5)+(4*0)+(3*4)+(2*7)+(1*3)=120
120 % 10 = 0
So 64504-73-0 is a valid CAS Registry Number.

Black-light-induced radical/ionic hydroxymethylation of alkyl iodides with atmospheric co in the presence of tetrabutylammonium borohydride

Kobayashi, Shoji,Kawamoto, Takuji,Uehara, Shohei,Fukuyama, Takahide,Ryu, Ilhyong

supporting information; experimental part, p. 1548 - 1551 (2010/07/06)

(Figure Presented) Tin-free radical/ionic hydroxymethylation of secondary and tertiary alkyl iodides proceeded efficiently in the presence of tetrabutylammonium borohydride as the hydrogen source under atmospheric pressure of CO In conjunction with photoirradiation using black light. Two possible mechanisms were proposed, both of which involve hybrid radical/ionic processes.

X=Y-ZH Systems as potential 1,3-dipoles. Part 52: Fused-ring forming electrophile induced oxime→nitrone→cycloaddition cascades

Ali Dondas,Grigg, Ronald,Thibault, Sylvie

, p. 7035 - 7045 (2007/10/03)

Electrophile induced cyclisation of oximes onto endocyclic alkenes and exo-methylene cycloalkanes occurs stereo- and regio-specifically generating cis-fused bicyclic nitrones in good yield. Subsequent facially selective cycloaddition with N-methylmaleimid
