Check Digit Verification of cas no

The CAS Registry Mumber 134297-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,2,9 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 134297-83:
(8*1)+(7*3)+(6*4)+(5*2)+(4*9)+(3*7)+(2*8)+(1*3)=139
139 % 10 = 9
So 134297-83-9 is a valid CAS Registry Number.

Photoinduced Alkylation Reaction of Benzoindole-4,9-dione with Arylalkenes

Nakagawa, Katsuhiko

, p. 1031 - 1033 (1991)

Photoreaction of 1-alkyl-2-methyl-1H-benzindole-4,9-diones (indolequinones) with arylalkenes in benzene gave 3-alkylated products.Irradiation of 1-allyl substituted indolequinone in benzene gave 1,3-hydrogen shift product in the presence or absence of arylalkenes.The fluorescence of 1,2-dimethyl-1H-benzindole-4,9-dione exhibits a large bathochromic shift in polar solvents, indicating polar charge-transfer character for its S1-state.
