Check Digit Verification of cas no

The CAS Registry Mumber 104050-01-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,0,5 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 104050-01:
(8*1)+(7*0)+(6*4)+(5*0)+(4*5)+(3*0)+(2*0)+(1*1)=53
53 % 10 = 3
So 104050-01-3 is a valid CAS Registry Number.

Reactivity of Compounds and the Crystal Structure of

Coronas, Juan Maria,Muller, Guillermo,Rocamora, Merce,Miravitlles, Carles,Solans, Xavier

, p. 2333 - 2342 (2007/10/02)

A series of compounds of the type trans- (L=PMe2Ph, R=C2Cl3, R'=Ph, C6H4OMe-4, C6H4Me-2, or -4, C6H2Me3-2,4,6; R=C6H4Cl-2, R'=C6H4Me-2 or C6H2Me3-2,4,6; R=C6H2Me3-2,4,6, R'=C6H4Me-2 or Ph; L=PEt3, R=C2Cl3, R'=C6H4Me-2, Ph, C6H4OMe-4, C6H4Cl-4, or C6H4Me-4; R=C6H4Cl-2, R'=Ph, C6H4Me-2 or-4; R=C6H4Me-2, R'=Ph, or C6H4Me-4; R=C6H2Me3-2,4,6, R'=C6H4Me-2) and cis- (bipy=2,2'-bipyridine) have been prepared.The proton n.m.r. signals of the ortho methyls of the mesityl ligand in the most hindered compound of the series appear overlapped despite the asymmetry of C2Cl3.The crystal structure of this compound indicates that this may be due to the phosphine aromatic rings.Ligand-exchange reactions of PMe2Ph by PEt3 in benzene,/ ->/, are complete in 0.5 h at room temperature, no intermediates being observed.The reverse process requires reflux for 10 h and in this case the intermediates can be obtained.If the groups R and R' contain ortho substituents the reaction does not take place.In refluxing benzene under nitrogen the stability of the organometallics containing PMe2Ph is greater than those with PEt3.Decomposition takes place via reductive elimination to give R-R' or via homolytic cleavage to give R-H and R'-H, the most favoured pathway depending on the size and electronegativity of the groups R and R'.The reductive-elimination process involves a previous step in which a phosphine group is lost.The addition of CO to solutions of (when R and R' possess ortho substituents) results in decomposition of the organometallics giving RCOR'.The compound is also decomposed but gives R-R'.When one ligands (R) contains an ortho substituent the corresponding two isomers (syn and anti) of the acyl derivative can be detected.The compounds cis- show a favourable associative decomposition pathway when R and R' are strong donor ligands.
