Check Digit Verification of cas no

The CAS Registry Mumber 1376654-81-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,6,6,5 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1376654-81:
(9*1)+(8*3)+(7*7)+(6*6)+(5*6)+(4*5)+(3*4)+(2*8)+(1*1)=197
197 % 10 = 7
So 1376654-81-7 is a valid CAS Registry Number.

Scalable, divergent synthesis of meroterpenoids via "borono- sclareolide"

Dixon, Darryl D.,Lockner, Jonathan W.,Zhou, Qianghui,Baran, Phil S.

, p. 8432 - 8435 (2012/07/14)

A scalable, divergent synthesis of bioactive meroterpenoids has been developed. A key component of this work is the invention of "borono- sclareolide", a terpenyl radical precursor that enables gram-scale preparation of (+)-chromazonarol. Subsequent synthetic operations on this key intermediate permit rapid access to a variety of related meroterpenoids, many of which possess important biological activity.
