Check Digit Verification of cas no

The CAS Registry Mumber 1610881-94-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,0,8,8 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1610881-94:
(9*1)+(8*6)+(7*1)+(6*0)+(5*8)+(4*8)+(3*1)+(2*9)+(1*4)=161
161 % 10 = 1
So 1610881-94-1 is a valid CAS Registry Number.

Copper-mediated tandem oxidative C(sp2)-H/C(sp)-H alkynylation and annulation of arenes with terminal alkynes

Dong, Jiaxing,Wang, Fei,You, Jingsong

, p. 2884 - 2887 (2014)

The copper-mediated tandem oxidative C(sp2)-H/C(sp)-H cross-coupling and intramolecular annulation of arenes with terminal alkynes has been developed, which offers a highly efficient approach to the 3-methyleneisoindolin-1-one scaffold. In this oxidative coupling process, Cu(OAc)2 acts as both the promoter and the terminal oxidant. This protocol features a wide substrate scope; high functional group tolerance; exclusive chemo-, regio-, and stereoselectivity; and simple, easily available, and inexpensive reaction system. The transformation has demonstrated for the first time that Cu(OAc)2 can be renewable after undergoing an oxidative reaction.
