Check Digit Verification of cas no

The CAS Registry Mumber 1439383-34-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,9,3,8 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1439383-34:
(9*1)+(8*4)+(7*3)+(6*9)+(5*3)+(4*8)+(3*3)+(2*3)+(1*4)=182
182 % 10 = 2
So 1439383-34-2 is a valid CAS Registry Number.

Functionalization of Csp3-H and Csp 2-H bonds: Synthesis of spiroindenes by enolate-directed ruthenium-catalyzed oxidative annulation of alkynes with 2-aryl-1,3-dicarbonyl compounds

Reddy Chidipudi, Suresh,Khan, Imtiaz,Lam, Hon Wai

supporting information, p. 12115 - 12119 (2013/01/16)

Ru(de) awakening: The synthesis of carbocycles by the ruthenium-catalyzed oxidative annulation of alkynes with 2-aryl cyclic 1,3-dicarbonyl substrates is described. Proceeding by the functionalization of C sp 3-H and C sp 2-H bonds, and the formation of an all-carbon quaternary center, the reaction provides a diverse range of spiroindenes in good yields with high levels of regioselectivity.
