Check Digit Verification of cas no

The CAS Registry Mumber 1158955-17-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,8,9,5 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1158955-17:
(9*1)+(8*1)+(7*5)+(6*8)+(5*9)+(4*5)+(3*5)+(2*1)+(1*7)=189
189 % 10 = 9
So 1158955-17-9 is a valid CAS Registry Number.

Rhodium-catalyzed hydroalkynylation of internal alkynes with silylacetylenes: An alkynylrhodium(I) intermediate generated from the hydroxorhodium(I) complex [Rh(OH)(binap)]2

Nishimura, Takahiro,Guo, Xun-Xiang,Ohnishi, Kohei,Hayashi, Tamio

, p. 2669 - 2672 (2008/09/19)

A highly selective hydroalkynylation of internal alkynes with silylacetylenes giving 1,3-enynes was realized by use of a hydroxorhodium catalyst. As a key intermediate in the catalytic cycle, an alkynylrhodium(I) complex was isolated and investigated for its structure and reactivity.
