Check Digit Verification of cas no
The CAS Registry Mumber 123408-87-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,4,0 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 123408-87:
(8*1)+(7*2)+(6*3)+(5*4)+(4*0)+(3*8)+(2*8)+(1*7)=107
107 % 10 = 7
So 123408-87-7 is a valid CAS Registry Number.

Synthesis of (+/-)-2-Oxo-seychellene and (+/-)-2-Oxo-4-epi-seychellene
Spitzner, Dietrich,Klein, Iris
, p. 63 - 68 (2007/10/02)
Aprotic Michael additions, which generate the functionalized bicyclooctane 8 from ethyl 2-methyl-2,3-butadienoate (10) and the lithium cyclohexadienolate 9a, are the key steps in the synthesis of 6 (and its 4-epimer). 6 was made from 8 in 10 steps.
