Check Digit Verification of cas no

The CAS Registry Mumber 1435467-13-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,5,4,6 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1435467-13:
(9*1)+(8*4)+(7*3)+(6*5)+(5*4)+(4*6)+(3*7)+(2*1)+(1*3)=162
162 % 10 = 2
So 1435467-13-2 is a valid CAS Registry Number.

Reaction of Donor-Acceptor Cyclobutanes with Indoles: A General Protocol for the Formal Total Synthesis of (±)-Strychnine and the Total Synthesis of (±)-Akuammicine

Feng, Liang-Wen,Ren, Hai,Xiong, Hu,Wang, Pan,Wang, Lijia,Tang, Yong

, p. 3055 - 3058 (2017)

A ligand-promoted catalytic [4+2] annulation reaction using indole derivatives and donor-acceptor (D-A) cyclobutanes is reported, thus providing an efficient and atom-economical access to versatile cyclohexa-fused indolines with excellent levels of diastereoselectivity and a broad substrate scope. In the presence of a chiral SaBOX ligand, excellent enantioselectivity was realized with up to 94 % ee. This novel synthetic method is applied as a general protocol for the total synthesis of (±)-akuammicine and the formal total synthesis of (±)-strychnine from the same common-core scaffold.
