Check Digit Verification of cas no

The CAS Registry Mumber 1189170-92-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,1,7 and 0 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1189170-92:
(9*1)+(8*1)+(7*8)+(6*9)+(5*1)+(4*7)+(3*0)+(2*9)+(1*2)=180
180 % 10 = 0
So 1189170-92-0 is a valid CAS Registry Number.

Enantioselective rhodium-catalyzed conjugate alkynylation of 5-benzylidene Meldrum's acids with TMS-acetylene

Fillion, Eric,Zorzitto, Alexander K.

supporting information; experimental part, p. 14608 - 14609 (2010/01/06)

(Chemical Equation Presented) The enantioselective alkynylation of benzylidene Meldrum's acids has been successfully achieved through rhodium-catalyzed addition of TMS-acetylene in the presence of bisphosphine ligand 3,5-Xylyl-MeOBIPHEP. The resulting Mel
