Check Digit Verification of cas no
The CAS Registry Mumber 870862-48-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,0,8,6 and 2 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 870862-48:
(8*8)+(7*7)+(6*0)+(5*8)+(4*6)+(3*2)+(2*4)+(1*8)=199
199 % 10 = 9
So 870862-48-9 is a valid CAS Registry Number.

, p. 10162 - 10165 (2007/10/03)
A new synthesis of epoxyketone 22 is described that is a key intermediate in Barton's synthesis of ovalicin (2), a powerful anti-angiogenetic inhibitor. The key process for the construction of 22 was ring-closing metathesis of olefins 11 and 12 obtained f
