Check Digit Verification of cas no

The CAS Registry Mumber 89780-88-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,7,8 and 0 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 89780-88:
(7*8)+(6*9)+(5*7)+(4*8)+(3*0)+(2*8)+(1*8)=201
201 % 10 = 1
So 89780-88-1 is a valid CAS Registry Number.

Novel photo-fragmentation of 3,3,6,6-tetra(p-methoxyphenyl)-1,2-dioxane through a C-O bond cleaved 1,6-diradical intermediate

Kamata, Masaki,Tanaka, Takehito,Kato, Mitsuaki

, p. 8181 - 8184 (2007/10/03)

Photolysis and thermolysis of 3,3,6,6-tetraaryl-1,2-dioxanes were investigated. The photolysis of 3,3,6,6-tetra(p-methoxyphenyl)-1,2-dioxane afforded 1,4,4-tri(p-methoxyphenyl)-3-buten-1-one and p-methoxyphenol through a novel C-O bond cleaved 1,6-diradical intermediate, while the thermolysis mainly afforded the expected decomposition product 4,4'-dimethoxybenzophenone through an O-O bond cleaved 1,6-dioxy diradical intermediate.
