Check Digit Verification of cas no

The CAS Registry Mumber 23056-94-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,0,5 and 6 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 23056-94:
(7*2)+(6*3)+(5*0)+(4*5)+(3*6)+(2*9)+(1*4)=92
92 % 10 = 2
So 23056-94-2 is a valid CAS Registry Number.

Gold-Catalyzed Rearrangement of Alkynyl Donor-Acceptor Cyclopropanes to Construct Highly Functionalized Alkylidenecyclopentenes

Chen, Huiyu,Zhang, Jing,Wang, David Zhigang

supporting information, p. 2098 - 2101 (2015/05/13)

A gold-catalyzed 1,7-addition-cyclization-elimination cascade sequence performed on a range of alkynyl-substituted donor-acceptor-type cyclopropanes provides facile entry to highly functionalized exo-alkylidenecyclopentenes under very mild conditions. Iso

Silver triflate-catalyzed cyclopropenation of internal alkynes with donor-/acceptor-substituted diazo compounds

Briones, John F.,Davies, Huw M. L.

supporting information; experimental part, p. 3984 - 3987 (2011/09/16)

Silver triflate was found to be an efficient catalyst for the cyclopropenation of internal alkynes using donor-/acceptor-substituted diazo compounds as carbenoid precursors. Highly substituted cyclopropenes, which cannot be synthesized directly via rhodium(II)-catalyzed carbenoid chemistry, can now be readily accessed.
