Check Digit Verification of cas no

The CAS Registry Mumber 109058-08-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,0,5 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109058-08:
(8*1)+(7*0)+(6*9)+(5*0)+(4*5)+(3*8)+(2*0)+(1*8)=114
114 % 10 = 4
So 109058-08-4 is a valid CAS Registry Number.

Photochemical Rearrangement of 2-Substituted 4-Alkylidene-2,3-epoxy-1-tetralone to 3-(2-oxoalkylidene)-1-indanone

Maruyama, Kazuhiro,Osuka, Atsuhiro,Nakagawa, Katsuhiko,Tabuchi, Kenzo,Shimizu, Hirohito,Suzuki, Hitomi

, p. 1849 - 1852 (1986)

Irradiation of 2-substituted 4-alkylidene-2,3-epoxy-1-tetralone results in the rearrangement to 3-(2-oxoalkylidene)-1-indanone or the E-Z isomerization around the double bound.These photoreactions are suggested to occur from the (?, ?*) triplet excited state.
