Check Digit Verification of cas no

The CAS Registry Mumber 18158-42-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,1,5 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 18158-42:
(7*1)+(6*8)+(5*1)+(4*5)+(3*8)+(2*4)+(1*2)=114
114 % 10 = 4
So 18158-42-4 is a valid CAS Registry Number.

Photo-induced electron-transfer reaction of aryl perfluoroalkanesulfonates with anilines

Chen, Qing-Yun,Li, Zhan-Ting

, p. 59 - 62 (1994)

Irradiation of mixtures of aryl perfluoroalkanesulfonates (RfSO3C6H4X-p, X = H, Cl and Me) (1) and aniline (2a), N,N-dimethylaniline (2b) or N,N-diethylaniline (2c) results in the formation of 2-coupling products 3 and 4-coupling products 4.However, in the reactions of 2b and 2c, in addition to 3 and 4, arenes 5 and N-methylaniline (6a) or N-ethylaniline (6b) are also detected.The presence of p-dinitrobenzene, But2NO and hydroquinone suppresses the reaction significantly.A photo-induced electron-transfer mechanism is proposed.
