Check Digit Verification of cas no

The CAS Registry Mumber 1393112-51-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,3,1,1 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1393112-51:
(9*1)+(8*3)+(7*9)+(6*3)+(5*1)+(4*1)+(3*2)+(2*5)+(1*1)=140
140 % 10 = 0
So 1393112-51-0 is a valid CAS Registry Number.

Naphthyl-l-α-amino acids via chemo-enzymatic dynamic kinetic resolution

D'Arrigo, Paola,Cerioli, Lorenzo,Fiorati, Andrea,Servi, Stefano,Viani, Fiorenza,Tessaro, Davide

, p. 938 - 944 (2012)

A double catalyst system (protease + base) was applied to the dynamic kinetic resolution (DKR) of isomeric 1- and 2-α-naphthyl-glycines and -alanines exploiting the in situ racemization of their thioesters. Due to the different C-acidity of the two sets of compounds, different experimental conditions have been devised to perform the simultaneous resolution/racemization process. In all cases, the racemic N-Boc-thioesters were converted into the aminoacids with an l-configuration almost quantitatively and with complete enantioselectivity. 2012 Elsevier Ltd.
