Check Digit Verification of cas no

The CAS Registry Mumber 1393110-64-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,3,1,1 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1393110-64:
(9*1)+(8*3)+(7*9)+(6*3)+(5*1)+(4*1)+(3*0)+(2*6)+(1*4)=139
139 % 10 = 9
So 1393110-64-9 is a valid CAS Registry Number.

A new approach to the bicyclo[3.3.1]nonane framework of huperzine A-like molecules via palladium-catalyzed intramolecular γ-arylation

Ding, Rui,Lu, Yunyu,Yao, Hequan,Sun, Bingfeng,Lin, Guoqiang

, p. 1097 - 1100 (2012/08/28)

In our synthetic studies toward huperzine A, a diastereoselective α′-alkylation of the α-amido-γ-methyl hexenone 4 was realized through a dianion intermediate which significantly enhanced the reactivity. Under the attempted Heck reaction conditions, an unexpected and unprecedented palladium-catalyzed intramolecular γ-arylation of 3 was observed, which generated 18 with bicyclo[3.3.1]nonane framework in satisfactory yield.
