Check Digit Verification of cas no

The CAS Registry Mumber 217434-05-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,7,4,3 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 217434-05:
(8*2)+(7*1)+(6*7)+(5*4)+(4*3)+(3*4)+(2*0)+(1*5)=114
114 % 10 = 4
So 217434-05-4 is a valid CAS Registry Number.

Nickel-catalyzed silaborative dimerization of alkynes

Suginome, Michinori,Matsuda, Takanori,Ito, Yoshihiko

, p. 5233 - 5235 (1998)

Double insertion of alkynes into the Si-B bond of (dimethylphenylsilyl)pinacolborane proceeded in the presence of nickel(0) catalysts to give cis,cis-1-silyl-4-boryl-1,3-butadiene derivatives in a regio- and stereo-selective manner. Involvement of (silyl)(2-boryl-1-alkylvinyl)nickel(II) intermediates in the silaborative dimerization reaction was suggested by the regiochemical preference as well as on the basis of reactions of the corresponding germylborane with alkynes in the presence of Ni, Pd, and Pt catalysts.
