Check Digit Verification of cas no

The CAS Registry Mumber 142819-34-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,8,1 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 142819-34:
(8*1)+(7*4)+(6*2)+(5*8)+(4*1)+(3*9)+(2*3)+(1*4)=129
129 % 10 = 9
So 142819-34-9 is a valid CAS Registry Number.

Anionic Cycloaddition with Thiophthalides: an Integrated Approach to the Synthesis of Olivin and Pillaromycinone

Majumdar, Gita,Pal, Ranjan,Murty, Kadiyala V. S. N.,Mal, Dipakranjan

, p. 309 - 316 (2007/10/02)

A systematic study of the potential reactivity of the thiophthalides 4 and 18 - 20 as 1,4-dipolar synthons, has shown that 3-phenylthiothiophthalide 19 is the best annulating agent for the preparation of tricyclic intermediates related to olivin.The reagent 19 underwent anionic cycloaddition with cyclohex-2-enone 5a in the presence of lithium tert-butoxide to give the anthracenones 24a and 25 in a combined yield of 90percent.
