Check Digit Verification of cas no

The CAS Registry Mumber 1380213-66-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,0,2,1 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1380213-66:
(9*1)+(8*3)+(7*8)+(6*0)+(5*2)+(4*1)+(3*3)+(2*6)+(1*6)=130
130 % 10 = 0
So 1380213-66-0 is a valid CAS Registry Number.

A concise and versatile double-cyclization strategy for the highly stereoselective synthesis and arylative dimerization of aspidosperma alkaloids

Medley, Jonathan William,Movassaghi, Mohammad

, p. 4572 - 4576 (2012/07/03)

Building cycles: A strategy for the concise, stereoselective synthesis of aspidosperma alkaloids and related structures via a common putative diiminium ion intermediate is reported. The approach enables the dimerization of aspidosperma-type structures at the sterically hindered C2 position. The intermediate is prepared in one step from the shown lactam through an electrophilic double-cyclization cascade (see scheme; Tf= trifluoromethanesulfonyl). Copyright
