Check Digit Verification of cas no

The CAS Registry Mumber 811867-68-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,1,1,8,6 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 811867-68:
(8*8)+(7*1)+(6*1)+(5*8)+(4*6)+(3*7)+(2*6)+(1*8)=182
182 % 10 = 2
So 811867-68-2 is a valid CAS Registry Number.

Chiral centers in the side chains of α-amino acids control the helical screw sense of peptides

Tanaka, Masakazu,Demizu, Yosuke,Doi, Mitsunobu,Kurihara, Masaaki,Suemune, Hiroshi

, p. 5360 - 5363 (2004)

Chirality on the side suffices: The screw sense of 310- and α-helices formed by the oligopeptides 1, which have no α-carbon chiral centers, is controlled by the chiral centers in their side chains. These results imply that just the side chain c
