Check Digit Verification of cas no

The CAS Registry Mumber 123123-47-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,1,2 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 123123-47:
(8*1)+(7*2)+(6*3)+(5*1)+(4*2)+(3*3)+(2*4)+(1*7)=77
77 % 10 = 7
So 123123-47-7 is a valid CAS Registry Number.

Asymmetric total synthesis of naturally occurring spirocyclic tetranorsesquiterpenoid lanceolactone A

Acharyya, Ranjan Kumar,Nanda, Samik

, p. 5027 - 5035 (2018/07/25)

Asymmetric total synthesis of naturally occurring γ-butenolide containing [4.4]spiro-tetrahydrofuran lanceolactone A has been reported in the present work. Bimetallic ("Pd-Cu") cascade cyclization was the crucial reaction employed for the construction of the γ-butenolide framework of the natural product. Subsequently, iodocyclization and reductive deiodination through a transfer hydrogenation reaction were applied to access the target molecule in an efficient manner.
