Check Digit Verification of cas no

The CAS Registry Mumber 239438-03-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,9,4,3 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 239438-03:
(8*2)+(7*3)+(6*9)+(5*4)+(4*3)+(3*8)+(2*0)+(1*3)=150
150 % 10 = 0
So 239438-03-0 is a valid CAS Registry Number.

Synthesis and characterization of new transition metal diynyl complexes

Moreno, Consuelo,Gomez, Jose L.,Medina, Rosa-Maria,Macazaga, Maria-Jose,Arnanz, Avelina,Lough, Alan,Farrar, David H.,Delgado, Salome

, p. 63 - 74 (1999)

The reaction of (η5-C5H5)Mo(CO)(dppe)Cl with LiC≡CC≡CSiMe3 yielded (η5-C5H 5)(CO)(dppe)MoC≡CC≡CSiMe3 (1b) and, as a by-product (η5-C5H5)Mo(CO)(dppe)Br (1a). Treatment of 1b with 0.2 equivalents of tetrabutylammonium fluoride or (η5-C5H5)Mo(CO)(dppe)Cl with HC≡CC≡CH gave the terminal butadiyne complex (η5-C5H5)(CO)(dppe)MoC≡CC≡CH (2). Complex 2 was deprotonated with sec-BuLi or lithium diisopropylamide, and the resulting anion (η5-C5H5)(CO)(dppe)MoC≡CC≡CLi (3) was trapped with Me3SiCl to regenerate 1b. The synthesis of Co2(CO)4L2(μ-η2-Me 3SiC2C≡CSiMe3) (L2 = dppa 4, 2PPh2Me 5) compounds can be achieved by two methods: from Co2(CO)6(μ-dppa) by reaction with Me3SiC≡CC≡CSiMe3 in 1:1 ratio to yield 4, or from Co2(CO)6(μ-η2-Me3SiC 2C≡CSiMe3) by reaction with dppa (1:1 ratio) and PPh2Me (1:2 ratio) to yield 4 and 5, respectively. When the Co2(CO)4(μ-dppa)(μ-η2-Me 3SiC2C≡CSiMe3) complex was treated with more Co2(CO)6(μ-dppa) the green di-substituted complex [Co2(CO)4(μ-dppa)]2(μ-η 2:μ-η2-Me3SiC2C 2SiMe3) (6) was obtained. Desilylation of 4 with Bu4NF gave Co2(CO)4(μ-dppa)(μ-η2-Me 3SiC2C≡CH) (7). All compounds synthesized have been characterized by analytical and spectroscopic data (IR, 1H-, 31P-, 13C-NMR, MS). In addition, compounds 1a and 4 were characterized by X-ray structure analysis.
