Check Digit Verification of cas no

The CAS Registry Mumber 41158-09-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,1,5 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 41158-09:
(7*4)+(6*1)+(5*1)+(4*5)+(3*8)+(2*0)+(1*9)=92
92 % 10 = 2
So 41158-09-2 is a valid CAS Registry Number.

Conformational study of α-arylethylamides of (-)-camphanic acid

Hamersak, Zdenko,Selestrin, Ana,Lesac, Andreja,Sunjic, Vitomir

, p. 1891 - 1897 (1998)

The absolute conformation and configuration of diastereomeric amides (4A,B-6A,B) of (1S,3R)-camphanic acid (lactone of 1-hydroxy-2,2,3- trimethylcyclopentan-1,3-dicarboxylic acid, (-)-camphanic acid 9) with α- arylethylamines 1-3 are deduced from 1H NMR data and MM2 calculations. The α-arylethyl group in diastereomers A and B adopt nearly opposite absolute conformations, stabilized by hydrogen bonding in the syn-oriented O-C(1)- C(6)-N-H unit, and repulsive interaction between the 1'C-Me group and the amide C=O group. The absolute configuration (1'S) is assigned to the 4A-6A diastereomers, and the (1'R)-configuration to the 4B-6B diastereomers; this assignment is confirmed by the preparation of 4A and 5A from enantiomerically pure (1'S)-α-arylethylamines 1 and 2, respectively. These results also enabled the assignment of pro-R (H(R)) and pro-S (H(S)) protons in the benzyl derivative 7.
