Check Digit Verification of cas no

The CAS Registry Mumber 76570-13-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,5,7 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 76570-13:
(7*7)+(6*6)+(5*5)+(4*7)+(3*0)+(2*1)+(1*3)=143
143 % 10 = 3
So 76570-13-3 is a valid CAS Registry Number.

Photochemistry of Methoxy-substituted Quinoline and Isoquinoline N-Oxides

Albini, Angelo,Fasani, Elisa,Dacrema, Lucia Maggi

, p. 2738 - 2742 (2007/10/02)

The photochemistry of quinoline 1-oxides and isoquinoline 2-oxides bearing a methoxy-group in the pyridine ring was investigated in protic and aprotic media.The formation of various photoisomers, viz. 3,1-benzoxazepines, 2(1H)-quinolones, N-(2-isocyanobenzyl)formamides, 4(1H)-quinolones, and 3-hydroxyquinolines from the different methoxyquinoline 1-oxides, and 1,3-benzoxazepines and 1(2H)-isoquinolones from the different methoxyisoquinoline 2-oxides, was observed along with deoxygenation and formation of products derived from hydration and decomposition of the primary products.The position of the methoxy-group has an important directing effect on the photoreactions.
