Check Digit Verification of cas no

The CAS Registry Mumber 102839-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,8,3 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 102839-89:
(8*1)+(7*0)+(6*2)+(5*8)+(4*3)+(3*9)+(2*8)+(1*9)=124
124 % 10 = 4
So 102839-89-4 is a valid CAS Registry Number.

Solvent effect on photoisomerisation of 3-methyl-1-phenylbutane-1,2-dione 2-oxime

Ikeda, Hirohito,Suzue, Takuya,Yukawa, Miho,Niiya, Tokihiro,Goto, Yoshinobu

, p. 969 - 971 (2002)

Photoisomerisation of (2E)- and (2Z)-3-methyl-1-phenylbutane-1,2-dione 2-oxime (MPBDO) in several solvents was studied. With increasing dielectric constants of solvents, kinetic constants of forward reactions (E-form→Z-form) did not change appreciably but
