Check Digit Verification of cas no

The CAS Registry Mumber 1438394-24-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,8,3,9 and 4 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1438394-24:
(9*1)+(8*4)+(7*3)+(6*8)+(5*3)+(4*9)+(3*4)+(2*2)+(1*4)=181
181 % 10 = 1
So 1438394-24-1 is a valid CAS Registry Number.

Enantio- and diastereoselective palladium catalysed arylative and vinylative allene carbocyclisation cascades

Li, Meiling,Hawkins, Alison,Barber, David M.,Bultinck, Patrick,Herrebout, Wouter,Dixon, Darren J.

, p. 5265 - 5267 (2013/06/27)

The enantioselective synthesis of heavily decorated spirolactams has been accomplished via an arylative or vinylative allene carbocyclisation cascade. Mediated by silver phosphate, a range of allene-linked pro-nucleophiles and aryl or vinyl iodides were reacted in the presence of catalytic Pd(OAc)2 and chiral bis(oxazoline) ligands to afford the spirolactam products in good yields and high enantio- and diastereoselectivities.
