Check Digit Verification of cas no

The CAS Registry Mumber 100181-13-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,1,8 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 100181-13:
(8*1)+(7*0)+(6*0)+(5*1)+(4*8)+(3*1)+(2*1)+(1*3)=53
53 % 10 = 3
So 100181-13-3 is a valid CAS Registry Number.

SOLID STATE PHOTOCHEMISTRY OF METHYL-SUBSTITUTED BENZOPHENONES

Ioto, Yoshikatsu,Matsuura, Teruo,Tabata, Kenichi,Ji-Ben, Meng,Fukuyama, Keiichi,et al.

, p. 1307 - 1312 (1987)

Upon UV irradiation in the solid-state 4,4'-dimethylbenzophenone (1a) underwent intermolecular hydrogen abstraction, followed by radical coupling, to give solely a dimeric product, 4-(2-hydroxy-2,2-di-p-tolyl-ethyl)-4'-methylbenzophenone (2).By contrast, 3,3'-dimethylbenzophenone (1b), 3,4'-dimethylbenzophenone (1c), and 4-methylbenzophenone (1d) were photostable under the same conditions.From X-ray crystallographic analysis of 1a and 1d, the distances between the C=O group and the nearby methyl C-H bond are 3.32 Angstroem for O...H and 3.87 Angstroem for C...C for reactive 1a and 2.77 (or 2.72) Angstroem for O...H and 4.39 (or 4.53) Angstroem for C...C for unreactive 1d.The angle C=O...H is 92 deg C for 1a and 121 or 137 deg C for 1d.The long C(*)C distance or/and the large C=O...H angle is probably responsible for the photoinertness of 1d.

EFFICIENT PHOTOCHEMICAL OXETANE FORMATION FROM 1-METHYL-2,4,5-TRIPHENYLIMIDAZOLE AND BENZOPHENONES

Ito, Yoshikatsu,Ji-Ben, Meng,Suzuki, Shin,Kusunaga, Yoshitaka,Matsuura, Teruo,Fukuyama, Keiichi

, p. 2093 - 2096 (2007/10/02)

In contrast to simple imidazoles, 1-methyl-2,4,5-triphenylimidazole (1) produced stable oxetane photoadducts 3b-e with good efficiency upon irradiation in the presence of benzophenone derivatives 2b-e in acetonitrile solution.Irradiation in the solid-phase was also studied.The oxetanes 3b-e readily underwent cycloreversion by acid catalysis or by heating.
