Check Digit Verification of cas no

The CAS Registry Mumber 77437-97-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,4,3 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 77437-97:
(7*7)+(6*7)+(5*4)+(4*3)+(3*7)+(2*9)+(1*7)=169
169 % 10 = 9
So 77437-97-9 is a valid CAS Registry Number.

RADIKALISCHE REAKTIONSWEGE BEI THERMISCH INDUZIERTEN UMSETZUNGEN VON ZIRCONOCENKOMPLEXEN

Erker, G.,Rosenfeldt, F.

, p. 1285 - 1292 (1982)

The formation of products 2, 3 and 4(a-l) from both the reaction of εta2-bezophenone zirconocene 1 with alkyl halides and the thermolysis of the α-(Cp2ZrCl)-substituted benzhydrylmethylether 9, the latter proceeding with anchimeric assistance of the metal, can be understood assuming a stepwise reaction path through radical intermediates.The proposed intermediate transition-metal benzophenone ketyl 12 exhibits a reaction pattern differing from analogous main-group-metal ketyls.
