Check Digit Verification of cas no

The CAS Registry Mumber 1217554-43-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,7,5,5 and 4 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1217554-43:
(9*1)+(8*2)+(7*1)+(6*7)+(5*5)+(4*5)+(3*4)+(2*4)+(1*3)=142
142 % 10 = 2
So 1217554-43-2 is a valid CAS Registry Number.

Copper-catalyzed decarboxylative cross-coupling of propiolic acids and terminal alkynes

Yu, Miao,Pan, Delin,Jia, Wei,Chen, Wei,Jiao, Ning

supporting information; experimental part, p. 1287 - 1290 (2010/04/27)

A copper-catalyzed decarboxylative cross-coupling reaction of propiolic acids with terminal alkynes is developed leading to unsymmetric 1,3-conjugated diynes under mild conditions. This method provides a novel decarboxylative cross-coupling for sp-sp bond formation. Compared to organic halides, only carbon dioxide is produced as by-products in this approach.
