Check Digit Verification of cas no

The CAS Registry Mumber 77826-33-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,8,2 and 6 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77826-33:
(7*7)+(6*7)+(5*8)+(4*2)+(3*6)+(2*3)+(1*3)=166
166 % 10 = 6
So 77826-33-6 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.
