Check Digit Verification of cas no

The CAS Registry Mumber 882303-11-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,2,3,0 and 3 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 882303-11:
(8*8)+(7*8)+(6*2)+(5*3)+(4*0)+(3*3)+(2*1)+(1*1)=159
159 % 10 = 9
So 882303-11-9 is a valid CAS Registry Number.

New synthesis of 2,3-diarylxanthones

Santos, Clementina M. M.,Silva, Artur M. S.,Cavaleiro, José A. S.

, p. 3095 - 3098 (2005)

A new synthesis for 2,3-diarylxanthones is described. This was accomplished by aldol condensation of 3-bromo-2-methylchromone with benzaldehydes leading to the formation of 3-bromo-2-styrylchromones, followed by Heck reaction with styrenes. Georg Thieme V

Efficient syntheses of new polyhydroxylated 2,3-diaryl-9H-xanthen-9-ones

Santos, Clementina M. M.,Silva, Artur M. S.,Cavaleiro, Jose A. S.

experimental part, p. 2642 - 2660 (2009/10/23)

A large number of hydroxylated 2,3-diaryl-9/i-xanthen-9ones have been synthesised by two different approaches, starting either from 3-brom.o-2-m.elhyl-4H-ch:rom.en-4-one or from. (E)-3-brom.o-2-styryl-4H-chrom. en-4-ones. The former method involves Heck r
