Check Digit Verification of cas no

The CAS Registry Mumber 56577-25-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,5,7 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 56577-25:
(7*5)+(6*6)+(5*5)+(4*7)+(3*7)+(2*2)+(1*5)=154
154 % 10 = 4
So 56577-25-4 is a valid CAS Registry Number.

Commercially available neat organozincs as highly reactive reagents for catalytic enantioselective addition to ketones and aldehydes under solvent free conditions

Hatano, Manabu,Mizuno, Tomokazu,Ishihara, Kazuaki

experimental part, p. 4417 - 4424 (2011/08/06)

Neat Et2Zn, Ph2Zn, and highly concentrated Me 2Zn are highly reactive organozinc reagents, which are commercially available in bulk quantities. We here report a catalytic enantioselective Et2Zn, Ph2Zn, and Me2Zn addition to ketones and aldehydes under solvent free or highly concentrated conditions without Ti(Oi-Pr)4 as a conventional activator of organozinc reagents. The desired optically active tertiary and secondary alcohols were obtained in good yield with high enantioselectivity when compared to the conventional solvent-use conditions. From the viewpoint of ecological and environmental reasons in green chemistry, this catalysis would be practical for not only academic but also industrial use.

Highly enantiospecific oxyfunctionalization of nonactivated hydrocarbon sites by perfluoro-cis-2-n-butyl-3-n-propyloxaziridine

Arnone, Alberto,Foletto, Stefania,Metrangolo, Pierangelo,Pregnolato, Massimo,Resnati, Giuseppe

, p. 281 - 284 (2008/02/14)

(equation presented) Nonactivated hydrocarbon sites of enantiopure compounds are oxyfunclionalized enantiospecifically by perfluoro-cis-2-n-butyl-3-n-propyloxaziridine under remarkably mild reaction conditions. The reaction occurs with retention of configuration at the oxidized stereogenic center, and the enantiospecificity is highly independent from both the carbon framework of the substrate and the presence of functional groups.
