Check Digit Verification of cas no

The CAS Registry Mumber 1221067-88-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,0,6 and 7 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1221067-88:
(9*1)+(8*2)+(7*2)+(6*1)+(5*0)+(4*6)+(3*7)+(2*8)+(1*8)=114
114 % 10 = 4
So 1221067-88-4 is a valid CAS Registry Number.

Construction of a tetracyclic butterfly-like scaffold: Palladium-catalyzed heck/arylation cascade

Kim, Ko Hoon,Lee, Hyun Seung,Kim, Sung Hwan,Kim, Se Hee,Kim, Jae Nyoung

, p. 2375 - 2380 (2010)

Controlled carbopalladation: Only slight changes in the starting material (see scheme) resulted in rather different compounds in palladium-catalyzed domino reactions. A novel tetracyclic butterfly-like scaffold was constructed in a one-pot reaction via the Pd-catalyzed 5-exo-trig carbopalladation and arylation cascade in high yield.
