Check Digit Verification of cas no

The CAS Registry Mumber 75684-74-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,6,8 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 75684-74:
(7*7)+(6*5)+(5*6)+(4*8)+(3*4)+(2*7)+(1*4)=171
171 % 10 = 1
So 75684-74-1 is a valid CAS Registry Number.

Host-Guest Complexation. 23. High Chiral Recognition of Amino Acid and Ester Guests by Hosts Containing One Chiral Element

Lingenfelter, David S.,Helgeson, Roger C.,Cram, Donald J.

, p. 393 - 406 (2007/10/02)

The chiral recognition properties of ten enantiomerically pure hosts toward the enantiomers of six different amino acids and their methyl esters have been examined.The hosts possessed the general structure (A)2D(OEOEO)2E, in which D is the chiral 1,1'-din
