Check Digit Verification of cas no

The CAS Registry Mumber 473253-67-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,3,2,5 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 473253-67:
(8*4)+(7*7)+(6*3)+(5*2)+(4*5)+(3*3)+(2*6)+(1*7)=157
157 % 10 = 7
So 473253-67-7 is a valid CAS Registry Number.

A new benzannulation reaction and its application in the multiple parallel synthesis of arylnaphthalene lignans

Flanagan, Stuart R,Harrowven, David C,Bradley, Mark

, p. 5989 - 6001 (2007/10/03)

A new aromatic annulation reaction based on sequential Horner-Emmons and Claisen condensation reactions is described. The method is high yielding and provides a rapid entry to arylnaphthalenes. The lignan natural products justicidin B 1, retrojusticidin B 2, taiwanin C 3, justicidin E 4, chinensin 5 and retrochinensin 6 have all been synthesised in good overall yield using this protocol, demonstrating its potential in multiple parallel synthesis. The selective oxidation of diols 34-36 to the corresponding retrolactones with barium manganate(VI) is also noteworthy.
