Check Digit Verification of cas no

The CAS Registry Mumber 1181219-13-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,1,2,1 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1181219-13:
(9*1)+(8*1)+(7*8)+(6*1)+(5*2)+(4*1)+(3*9)+(2*1)+(1*3)=125
125 % 10 = 5
So 1181219-13-5 is a valid CAS Registry Number.

Nickel-catalyzed C-H alkenylation and alkylation of 1,3,4-oxadiazoles with alkynes and styrenes

Mukai, Tomoya,Hirano, Koji,Satoh, Tetsuya,Miura, Masahiro

experimental part, p. 6410 - 6413 (2009/12/06)

(Chemical Equation Presented) The addition reaction of 1,3,4-oxadiazoles to alkynes via C-H bond cleavage efficiently proceeds in the presence of a nickel catalyst. This direct coupling allows a facile access to alkenyl-substituted oxadiazoles. The reaction with styrenes in place of alkynes is also available to selectively afford the corresponding branched adducts.
