Check Digit Verification of cas no

The CAS Registry Mumber 109825-43-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,8,2 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 109825-43:
(8*1)+(7*0)+(6*9)+(5*8)+(4*2)+(3*5)+(2*4)+(1*3)=136
136 % 10 = 6
So 109825-43-6 is a valid CAS Registry Number.

The Constituents of Eucommia ulmoides OLIV. VI. Isolation of a New Sesquilignan and Neolignan Glycosides

Deyama, Takeshi,Ikawa, Takako,Kitagawa, Shizuka,Nishibe, Sansei

, p. 1803 - 1807 (2007/10/02)

A new sesquilignan glycoside, syringylgycerol-β-syringaresinol ether 4'', 4'''-di-O-β-D-glucopyranoside (1), and a new neolignan glycoside, dehydrodiconiferyl alcohol 4,γ'-di-O-β-D-glucopyranoside (2), were isolated from the bark of Eucommia ulmoides OLIV. (Eucommiaceae), together with a known neolignan glycoside, citrusin B (3).Their structures were determined on the basis of chemical evidence and spectroscopic analyses. Keywords---Eucommia ulmoides; lignan; sesquilignan; neolignan; dihydrobenzofuran; syringylglycerol-β-syringaresinol ether 4'',4'''-di-O-β-D-glucopyranoside; dehydrodiconiferyl alcohol 4,γ'-di-O-β-D-glucopyranoside; 13C-NMR
