Check Digit Verification of cas no

The CAS Registry Mumber 16611-09-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,6,1 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 16611-09:
(7*1)+(6*6)+(5*6)+(4*1)+(3*1)+(2*0)+(1*9)=89
89 % 10 = 9
So 16611-09-9 is a valid CAS Registry Number.

Oxy-Functionalization of Adamante-1-acetic Acid and Adamantane-1-carboxylic Acid by the Ferrous Iron-Molecular Oxygen System in Aqueous Solution

Miura, Toshiaki,Shibata, Kunihiko,Sawaya, Takuji,Kimura, Michiya

, p. 67 - 73 (2007/10/02)

Oxygenation reactions of adamantanes with ferrous iron-molecular oxygen in phosphate buffer were investigated and the structures of the products were elucidated.In the reaction of adamantane-1-acetic acid (1a), five oxygenated products, the C(2)-oxo, C(4)-oxo, C(2),C(6)-dioxo, C(4)-ol, and C(3)-ol derivatives, were obtained.Similar oxygenation also occurred in the reaction of adamantane-1-carboxylic acid (2a) to give three products, the C(4)-oxo, C(4)-ol, and C(3)-ol derivatives.The oxy-functionalization of 1a and 2a in 0.5M phosphate buffer (pH 6.8) was found to occur almost quantitatively on addition of an appropriate amount of ferrous iron.
