Check Digit Verification of cas no

The CAS Registry Mumber 102382-32-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,3,8 and 2 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 102382-32:
(8*1)+(7*0)+(6*2)+(5*3)+(4*8)+(3*2)+(2*3)+(1*2)=81
81 % 10 = 1
So 102382-32-1 is a valid CAS Registry Number.

Tannins and Related Compounds. Part 37.1 Isolation and Structure Elucidation of Elaeocarpusin, a Novel Ellagitannin from Elaeocarpus sylvestris var. Ellipticus

Tanaka, Takashi,Nonaka, Gen-ichiro,Nishioka, Itsuo,Miyahara, Kazumoto,Kawasaki, Toshio

, p. 369 - 376 (2007/10/02)

A new hydrolysable tannin, elaeocarpusin, isolated from the leaves of Elaeocarpus sylvestris var.Ellipticus, has been characterized on the basis of chemical, spectroscopic, and X-ray analyses to be a novel ellagitannin in which a unique acid ester group probably derived by a condensation of a hexahydroxydiphenoyl group and dehydroascorbic acid is attached to the 2,4-positions of 1-O-galloyl-3,6-(R)-hexahydroxydiphenoyl-D-glucopyranose (corilagin).This structural feature suggest the possibility of the participation of dehydroascorbic acid as a co-enzyme in oxidative metabolism of the hexahydroxydiphenoyl group to the corresponding dehydro group.
