Check Digit Verification of cas no

The CAS Registry Mumber 1179645-58-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,9,6,4 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1179645-58:
(9*1)+(8*1)+(7*7)+(6*9)+(5*6)+(4*4)+(3*5)+(2*5)+(1*8)=199
199 % 10 = 9
So 1179645-58-9 is a valid CAS Registry Number.

Auto de-bromine-coupling reactions of 1-aryl-7-bromocycloheptenes

Lee, Gon-Ann,Lee, Hsin-Yi,Wang, Wen-Chieh,Cherng, Chih-Hwa

, p. 2956 - 2961 (2014/04/17)

Auto de-bromine-coupling reactions of 1-aryl-7-bromocycloheptenes to a new series of [7-6-6] tricyclic system were described. A variety of substituents at the para-position of the phenyl were amenable to this transformation, including electron-donating groups and halides. The presence of electron-donating groups resulted in a more efficient reaction, with higher yields than the case of halides.
