Check Digit Verification of cas no

The CAS Registry Mumber 1108697-85-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,0,8,6,9 and 7 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1108697-85:
(9*1)+(8*1)+(7*0)+(6*8)+(5*6)+(4*9)+(3*7)+(2*8)+(1*5)=173
173 % 10 = 3
So 1108697-85-3 is a valid CAS Registry Number.

Gold catalysis: Non-spirocyclic intermediates in the conversion of furanynes by the formal insertion of an alkyne into an aryl-alkyl C-C single bond

Hashmi, A. Stephen K.,Haeffner, Tobias,Yang, Weibo,Pankajakshan, Sreekumar,Schaefer, Sascha,Schultes, Lara,Rominger, Frank,Frey, Wolfgang

supporting information, p. 10480 - 10486 (2012/11/07)

It takes al-kynes: The formation of furyl-substituted heterocycles from furanynes with donor groups on the furan-alkyne tether and mechanistic control experiments indicate the involvement of open-chained carbenium ions in the overall insertion of an alkyne into a C-C bond, rather than the usual spirocyclic intermediates (see scheme).
