Check Digit Verification of cas no

The CAS Registry Mumber 174463-50-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,4,6 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 174463-50:
(8*1)+(7*7)+(6*4)+(5*4)+(4*6)+(3*3)+(2*5)+(1*0)=144
144 % 10 = 4
So 174463-50-4 is a valid CAS Registry Number.

L-Methionine related 1-amino acids by acylase cleavage of their corresponding N-acetyl-DL-derivatives

Bommarius, Andreas S.,Drauz, Karlheinz,Guenther, Kurt,Knaup, Guenter,Schwarm, Michael

, p. 3197 - 3200 (1997)

Acylase I from Aspergillus oryzae is an even more useful enzyme than suggested so far. Besides standard amino acids such as L-Met, L-Val and L-Phe, a number of additional sulfur- and selenium-containing amino acids can be obtained at useful reaction rates and in very high enantiomeric purity by kinetic resolution of the respective N-acetyl-DL-amino acids.
