Check Digit Verification of cas no

The CAS Registry Mumber 256464-92-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,6,4,6 and 4 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 256464-92:
(8*2)+(7*5)+(6*6)+(5*4)+(4*6)+(3*4)+(2*9)+(1*2)=163
163 % 10 = 3
So 256464-92-3 is a valid CAS Registry Number.

Toward creation of a universal NMR database for the stereochemical assignment of acyclic compounds: Proof of concept

Lee, Jinhwa,Kobayashi, Yoshihisa,Tezuka, Kenichi,Kishi, Yoshito

, p. 2181 - 2184 (2008/02/09)

Oasomycin B: R = α-D-mannosyl Using the C.5-C.10 portion of the oasomycin class of natural products, the reliability and usefulness of an NMR database for the stereochemical assignment of acyclic compounds has been demonstrated. The predicted relative stereochemistry based on the NMR database has unambiguously been established via synthesis.
