Check Digit Verification of cas no

The CAS Registry Mumber 405-70-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,0 and 5 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 405-70:
(5*4)+(4*0)+(3*5)+(2*7)+(1*0)=49
49 % 10 = 9
So 405-70-9 is a valid CAS Registry Number.

Reductive etherification of aldehydes photocatalyzed by dicarbonyl pentamethylcyclopentadienyl iron complexes

Argouarch, Gilles,Grelaud, Guillaume,Roisnel, Thierry,Humphrey, Mark G.,Paul, Frédéric

, p. 5015 - 5018 (2012)

The reductive etherification of aldehydes can be performed by the reaction with dialkylmethylsilanes in the presence of new iron(II) piano-stool catalysts of general formula Cp*Fe(CO)2Ar (Cp * = η5-C5Me5; Ar = Ph, 4-C6H4OCH3, 4-C6H4CH 3, Fc). This transformation is promoted by UV light and affords a simple route for the preparation of unsymmetrical alkyl ethers.

SUR LA RELATION D'ACREE. VII. CORRELATION DE HAMMETT AVEC LES CONSTANTES DE VITESSE DES "IONS" ET DES "PAIRES D'IONS" - RESPECTIVEMENT ki et kp - DANS UNE REACTION DE SUBSTITUTION NUCLEOPHILE SUR DES SUBSTRATS BENZYLIQUES

Cayzergues, P.,Georgoulis, C.,Mathieu, G.

, p. 63 - 70 (2007/10/02)

The differentiation of the respective contributions of "ions" and "ion pairs", to the reaction of several benzylic chlorides with anionic nucleophiles, showed the possibility of establishing Hammett correlations with rate constants ki and kp and revealed the existence of two different mechanistic pathways with different ρ values: ρ = 2.2 for the "ions" and ρ = - 0.6 for the "ion pairs".
