Check Digit Verification of cas no

The CAS Registry Mumber 256229-11-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,6,2,2 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 256229-11:
(8*2)+(7*5)+(6*6)+(5*2)+(4*2)+(3*9)+(2*1)+(1*1)=135
135 % 10 = 5
So 256229-11-5 is a valid CAS Registry Number.

Almond oxynitrilase-catalyzed transformation of aldehydes is strongly influenced by naphthyl and alkoxy substituents

Roda, Gabriella,Riva, Sergio,Danieli, Bruno

, p. 3939 - 3949 (2007/10/03)

Different α- and β-substituted aldehydes have been submitted to the catalytic action of almond oxynitrilase (PaHNL), in order to explore the influence of a stereocenter already present in the substrate on the selectivity of this enzyme. The results indicate that naphthyl and alkoxy substituents in the α- and also in the β-position to the aldehyde group significantly influence the stereochemical outcome of the PaHNL-catalyzed transformation.
