Check Digit Verification of cas no

The CAS Registry Mumber 17398-06-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,3,9 and 8 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 17398-06:
130 % 10 = 0
So 17398-06-0 is a valid CAS Registry Number.

Synthesis and absolute structure of (-)-umtatin

Yamaguchi, Seiji,Kobayashi, Masahide,Harada, Shin-Ichiro,Miyazawa, Masahiro,Hirai, Yoshiro

, p. 863 - 868 (2008)

A new preparation of 2-(hydroxymethyl)chromones was developed via the new regio-selective six-membered cyclization of 1-[o-(tert-butyldimethylsiloxy) phenyl]but-2-yn-1-ones by a three-step treatment with 1) diethylamine (activation of the γ-position), 2) KF-18-crown-6 (deprotection), and 3) silica-gel (cyclization). A naturally occurring chiral hydroxymethylfurochromone, (-)-umtatin, was synthesized starting from chiral (R)-(-)-2-isopropenyl-4,6-dimethoxy-2,3-dihydrobenzofuran, and the absolute structure was determined to R.
