Check Digit Verification of cas no

The CAS Registry Mumber 149157-25-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,1,5 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 149157-25:
(8*1)+(7*4)+(6*9)+(5*1)+(4*5)+(3*7)+(2*2)+(1*5)=145
145 % 10 = 5
So 149157-25-5 is a valid CAS Registry Number.

A high-throughput screening protocol for fast evaluation of enantioselective catalysts

Wolf, Christian,Hawes, Pili A.

, p. 2727 - 2729 (2002)

A new high-throughput screening protocol that allows fast evaluation of enantioselective catalysts has been developed. The usefulness of norephedrine-derived β-amino alcohols as catalysts for the enantioselective alkylation of prochiral aldehydes has been determined by simultaneous screening of three representative substrates. GC analysis of the crude product mixture using a selectively modified cyclodextrin as the chiral stationary phase avoids timeconsuming workup procedures. The chemical yield, enantioselectivity, substrate specificity, and catalytic activity of the chiral catalysts as well as the induced absolute configuration have been determined in a single screening experiment and two short GC runs.
