Check Digit Verification of cas no

The CAS Registry Mumber 218909-18-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,8,9,0 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 218909-18:
(8*2)+(7*1)+(6*8)+(5*9)+(4*0)+(3*9)+(2*1)+(1*8)=153
153 % 10 = 3
So 218909-18-3 is a valid CAS Registry Number.

Directional Fe-COS intermolecular interaction leading to chain-like crystal packing in binuclear Fe(0)-M(II) (M=Hg, Cd) complexes with 2-(diphenylphosphino)thiazole

Kuang, Shan-Ming,Zhang, Zheng-Zhi,Xue, Feng,Mak, Thomas C.W.

, p. 51 - 56 (2007/10/03)

A new thiazole-based phosphine ligand was designed to construct heterobinuclear complexes (CO)3Fe(μ-Ph2PNS)2MX2 (M=Hg, X=SCN; M=Cd, X=I; Ph2PNS=2-(diphenylphosphino)thiazole), in which weak Fe-COS intermolecular interaction led to chain-like molecular packing in the solid state.

Phosphorus ylide-containing niobium complexes: Preparation and characterization of homo- and heteronuclear compounds with an α-keto ylide ligand

Antinolo,Carrillo-Hermosilla,Diez-Barra,Fernandez-Baeza,Lara-Sanchez,Otero,Tejeda

, p. 97 - 105 (2007/10/03)

The reactions have been studied between [{NbCl3(dme)}n] or [NbCl3(dme)(RCCR′)] with a heterocycle containing α-keto stabilized phosphorus ylide, 2-TCMP=[{2-thiazolylcarbonyl}methylene]triphenylphosphorane, and these reactions give the α-keto ylide-containing niobium complexes [{NbCl3(2-TCMP)}2] (1) and [NbCl3(2-TCMP)(RCCR′)], R=R′=Ph (2); R=R′=Me (3); R=R′=Et (4); R=Ph, R′=Me (5); R=Ph, R′=Et (6); R=Ph, R′=Pr (7); R=Ph, R′=SiMe3 (8), respectively. The reactivity of 5 towards different reagents has also been investigated. Compound 5 reacts with MeLi to give, through a deprotonation process of a phenyl ring, the ortho-metallated complex [NbCl2{NOSC4H2CHPPh2(C 6H4)-O,N}]2 (9), with the loss of the alkyne ligand. Furthemore, 5 reacts with [AuPPh2R]CF3SO3 and AgCF3SO3 to give the heterometallic complexes [NbCl3(2-TCMP)Au PPh2R]2 (CF3SO3)2, R=Ph (10), R=C3H2SN (11), and [NbCl3(2-TCMP)Ag]2 (CF3SO3)2 (12), respectively, with the loss of the alkyne ligand in each case.
