Check Digit Verification of cas no

The CAS Registry Mumber 709030-17-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,0,9,0,3 and 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 709030-17:
(8*7)+(7*0)+(6*9)+(5*0)+(4*3)+(3*0)+(2*1)+(1*7)=131
131 % 10 = 1
So 709030-17-1 is a valid CAS Registry Number.

A novel, convenient synthesis of the 3-O-β-D- and 4′-O-β -D-glucopyranosides of trans-resveratrol

Learmonth, David A.

, p. 1565 - 1575 (2007/10/03)

trans-Resveratrol-3-O-β-D-glucupyranoside (trans-piceid, 2) and trans-resveratrol-4′-O-β-D-glucupyranoside (trans-resveratroloside 3) are the naturally occurring O-glucoside conjugates of the polyphenolic stilbenoid trans-resveratrol 1. Recently, attention has been drawn towards the interesting biological properties of the glucoside conjugates 2 and 3 as well as those of the aglycone 1. The fact that only limited quantities can be obtained by extraction from natural sources has prompted the development of novel syntheses of 2 and 3, based on a convergent Heck-coupling strategy, which now conveniently allows for the preparation of multi-milligram to gram quantities of each.
