Check Digit Verification of cas no

The CAS Registry Mumber 1569438-22-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,9,4,3 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1569438-22:
(9*1)+(8*5)+(7*6)+(6*9)+(5*4)+(4*3)+(3*8)+(2*2)+(1*2)=207
207 % 10 = 7
So 1569438-22-7 is a valid CAS Registry Number.

Copper-catalyzed domino route to natural nostoclides and analogues: A total synthesis of nostoclides i and II

Ngi, Samuel Inack,Petrignet, Julien,Duwald, Romain,El Hilali, El Mostafa,Abarbri, Mohamed,Duchêne, Alain,Thibonnet, Jér?me

, p. 2936 - 2941 (2014/03/21)

An original and convenient domino route to natural nostoclides I and II has been developed using a two-step sequence consisting of a copper-cat-alyzed tandem reaction associated with Suzuki cross-coupling. The methodology employed for this total synthesis appeared to be an interesting and suffi-ciently flexible tool to allow the synthesis of numer-ous analogues of these nostoclides.
