Check Digit Verification of cas no

The CAS Registry Mumber 797-98-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,9 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 797-98:
(5*7)+(4*9)+(3*7)+(2*9)+(1*8)=118
118 % 10 = 8
So 797-98-8 is a valid CAS Registry Number.

Organophosphorus compounds, 145 - Synthesis and reactivity of a polycyclic, oxa-bridged phosphaalkene

Ruf, Sven G.,Bergstr??er, Uwe,Regitz, Manfred

, p. 2219 - 2225 (2000)

Thermolysis of 2,3-diphenylindenone 2,3-epoxide (1) in the presence of tert-butylphosphaalkyne (3) proceeds through a regiospecific 1,3-dipolar cycloaddition of the phosphaalkyne to the carbonyl ylide intermediate to furnish the polycyclic phosphaalkene derivative 4. Compound 4 exhibits a remarkable - and for phosphaalkenes unusual - stability: thus, it can be stored for several days and no decomposition can be observed even in the absence of inert gas protection. The phosphaalkene 4 reacts with 1,3-dipoles such as ethyl diazoacetate (8) by formal transfer of its phosphaalkene unit to afford the 1,2,4-diazaphosphole 10. Addition of lithium alkoxides to the phosphaalkene unit of the polycyclic compound 4 occurs diastereoselectively to give the novel phosphinites 13 and 14. In this context it should be mentioned that the choice of the lithium alkoxide has a decisive influence on the preferred formation of one diastereomer of the phosphinite.

A NEW PHOTO/THERMOCHROMIC SOLID COMPOUND OF THE INDENONE OXIDE FAMILY

Hadjoudis, E.,Pulima, I.

, p. 29 - 36 (2007/10/02)

A new strong photochromic solid compound, a 3-ketone of the 2,3-diphenylindenone oxide, has been prepared for first time.The new compound exhibits very strong photochromic and thermochromic phenomena.
