Check Digit Verification of cas no

The CAS Registry Mumber 1341216-62-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,1,2,1 and 6 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1341216-62:
(9*1)+(8*3)+(7*4)+(6*1)+(5*2)+(4*1)+(3*6)+(2*6)+(1*2)=113
113 % 10 = 3
So 1341216-62-3 is a valid CAS Registry Number.

Asymmetric synthesis of andavadoic acid via base-catalyzed 5-exo-tet cyclization of a β-hydroperoxy epoxide

Barnych, Bogdan,Fenet, Bernard,Vatèle, Jean-Michel

, p. 334 - 340 (2013/01/15)

The first total synthesis of andavadoic acid, a naturally occurring five-membered ring peroxide, and its absolute configuration assignment are reported. Central to this venture was the development of an effective synthesis of a key β-hydroperoxy epoxy ester from (R)-epichlorohydrin via chemoselective methylenation with Nysted reagent in the presence of Ti(Oi-Pr)2Cl2 and chemo- and regioselective Mukaiyama-Isayama peroxidation. This approach also featured the construction of the 1,2-dioxolane ring system by an efficient base-promoted 5-exo epoxide opening by a hydroperoxy group.
