Check Digit Verification of cas no

The CAS Registry Mumber 1432521-31-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,2,5,2 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1432521-31:
(9*1)+(8*4)+(7*3)+(6*2)+(5*5)+(4*2)+(3*1)+(2*3)+(1*1)=117
117 % 10 = 7
So 1432521-31-7 is a valid CAS Registry Number.

Domino C-H functionalization reactions of gem-dibromoolefins: Synthesis of N-fused benzo[c]carbazoles

Huang, Richard Y.,Franke, Patrick T.,Nicolaus, Norman,Lautens, Mark

supporting information, p. 4395 - 4402 (2013/06/27)

A palladium-catalyzed domino transformation of gem-dibromoolefins leading to novel polycyclic benzo[c]carbazoles is described. A unique feature of the current reaction is the participation of both bromides in C-H functionalization processes. Mechanistic studies were conducted to ascertain the sequence of reaction events, and the results indicate that the (Z)-bromide likely reacts in preference to the (E)-bromide.
