Check Digit Verification of cas no

The CAS Registry Mumber 1432620-60-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,2,6,2 and 0 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1432620-60:
(9*1)+(8*4)+(7*3)+(6*2)+(5*6)+(4*2)+(3*0)+(2*6)+(1*0)=124
124 % 10 = 4
So 1432620-60-4 is a valid CAS Registry Number.

Total synthesis and structure-activity relationship study of the potent cAMP signaling agonist (-)-alotaketal A

Huang, Jinhua,Yang, Jessica R.,Zhang, Jin,Yang, Jiong

, p. 3212 - 3222 (2013/06/05)

A detailed account of the first total synthesis of alotaketal A, a tricyclic spiroketal sesterterpenoid that potently activates the cAMP signaling pathway, is provided. The synthesis employs both intra- and intermolecular reductive allylation of esters for assembling one of the fragments and their coupling. A Hg(OAc)2-mediated allylic mercuration is used to introduce the C22-hydroxyl group. The subtle influence of substituents over the course of the spiroketalization process is revealed. The synthesis confirms the relative and absolute stereochemistry of (-)-alotaketal A and allows verification of alotaketal A's effect over cAMP signaling using reporter-based FRET imaging assays with HEK 293T cells. Our studies also revealed alotaketal A's unique activity in selectively targeting nuclear PKA signaling in living cells. The Royal Society of Chemistry 2013.
