Check Digit Verification of cas no

The CAS Registry Mumber 104806-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,8,0 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 104806-83:
(8*1)+(7*0)+(6*4)+(5*8)+(4*0)+(3*6)+(2*8)+(1*3)=109
109 % 10 = 9

Isolation of -linked Biflavanoids from Acacia melanoxylon: First Examples of a New Class of Single Ether-linked Proanthocyanidin Dimers

Foo, Lai Yeap

, p. 1505 - 1506 (1989)

The isolation of the unique -linked biflavanoids, -bis(2,3-cis-3,4-trans-3,3',4',7,8-pentahydroxyflavan) (5) and the isomeric 2,3-cis-3,4-trans-3,3',4',7'8-pentahydroxyflavan--2,3-cis-3,4-cis-3,3,4',7,8-pentahydroxyflavan (6), from the heartwood of Acacia melanoxylon further extends the heterogeneity of the interflavanoid linkage among natural proanthocyanidin dimers and oligomers.
