Check Digit Verification of cas no

The CAS Registry Mumber 20195-60-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,1,9 and 5 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20195-60:
(7*2)+(6*0)+(5*1)+(4*9)+(3*5)+(2*6)+(1*0)=82
82 % 10 = 2
So 20195-60-2 is a valid CAS Registry Number.

Formation of the first monoanion and dianion of stannole

Saito, Masaichi,Haga, Ryuta,Yoshioka, Michikazu

, p. 1002 - 1003 (2002)

The first syntheses of mono- and dianions of stannole were accomplished by transmetallation or reduction of the novel bi(1,1-stannole).

Li deposited on LiCl: An efficient reducing agent

Laperriere, Leif E.,Martin, Caleb D.,Su, Xiaojun

supporting information, p. 14913 - 14915 (2021/09/04)

Lithium was deposited onto lithium chloride powder in a ～5% weight/weight ratio. This material serves as a source of elemental lithium with benefits over bulk lithium alternatives including increased mass to facilitate measurement for small scale reactions and increased surface area. The Li/LiCl material is applied in the synthesis of a dilithiobutadienide that is transformed into a stannole with a drastic decrease in reaction time and notable increase in yield over commercial lithium granules.

Synthesis and structures of bi(1,1-stannole)s

Saito, Masaichi,Haga, Ryuta,Yoshioka, Michikazu

, p. 3750 - 3755 (2007/10/03)

The synthesis and structures of bi(1,1-stannole)s are described. Treatment of 1-bromo-4-(dibromophenylstannyl)-1,3-butadiene with tert-butyllithium gives the bi(1,1-stannole) having a phenyl group on each tin atom, whereas treatment of 1-bromo-4-(tribromostannyl)-1,3-butadiene with phenyl- or bulky alkyllithiums gives the bi(1,1-stannole) having a phenyl or an alkyl group on each tin atom. The X-ray analysis of the tert-butyl-substituted bi(1,1-stannole) is also described. All bi(1,1-stannole)s display two shoulder absorption bands due to π-π* and σ-π* transitions.

Electrochemical and photophysical properties of a series of group-14 metalloles

Ferman, Justin,Kakareka, Joseph P.,Klooster, Wim T.,Mullin, Jerome L.,Quattrucci, Joseph,Ricci, John S.,Tracy, Henry J.,Vining, William J.,Wallace, Scott

, p. 2464 - 2472 (2008/10/08)

A series of six group-14 dimethyl- or diphenyl-tetraphenylmetallacyclopentadienes were synthesized and characterized by their spectroscopic and electrochemical properties. The group-14 elements investigated were silicon, germanium, and tin. (The compounds are designated according to the heteroatom and the substituent on the heteroatom, i.e., SiMe, SiPh, SnPh.) Five of the six compounds luminesce in both the solid state and in solution. The emission maxima of SiPh, GePh, and SnPh are invariant to a change in the heteroatom, while for SiMe, GeMe, and SnMe there is a strong dependence of the emission maxima on the identity of the heteroatom. SiMe emits at a longer wavelength than GeMe, while SnMe is not luminescent. The dramatic luminescence difference between the two tin compounds was investigated. 13C NMR coupling to 119/117Sn, observed in both SnMe and SnPh, was used to make 13C NMR resonance assignments. Qualitative results of semiempirical molecular orbital calculations support the 13C NMR assignments. The crystal structure data for SnPh was obtained at 20 °C: a = 10.353(2) A?, b = 16.679(2) A?, c = 9.482(1) A?, α = 99.91(1)°, β = 106.33(1)°, γ = 77.80(1)° with Z = 2 in space group P1. It is proposed that the increased electron density at tin in SnMe is responsible for the deactivation of the emissive state. The presence of phenyl substituents in SnPh serves to stabilize the emissive state and luminescence is observed.
