Check Digit Verification of cas no

The CAS Registry Mumber 92104-69-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,1,0 and 4 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 92104-69:
(7*9)+(6*2)+(5*1)+(4*0)+(3*4)+(2*6)+(1*9)=113
113 % 10 = 3
So 92104-69-3 is a valid CAS Registry Number.

MODIFICATION OF SINGLET CARBENE REACTIVITIES BY SOLVENT

Tomoika, H.,Ozaki, Y.,Izawa, Y

, p. 4987 - 4994 (2007/10/02)

The solvent effect on the reactivity of singlet carbenes has been investigated.Competition reactions between pairs of alcohols for arylcarbenes in various solvents indicates that the O-H insertion selectivity is influenced only by 1,4-dioxane.Thus, phenylcarbene is some 33 times more reactive toward methanol relative to t-butyl alcohol in 90 molpercent dioxane than without solvent.Similar competition reactions between alcohol and olefin indicate that the O-H insertion-addition selectivities of arylcarbenes are considerably altered by dioxane.These results are interpreted as indicating that dioxane stabilizes singlet carbenes by complexing with its ione pairs of electrons.
