Check Digit Verification of cas no

The CAS Registry Mumber 871979-80-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,1,9,7 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 871979-80:
(8*8)+(7*7)+(6*1)+(5*9)+(4*7)+(3*9)+(2*8)+(1*0)=235
235 % 10 = 5
So 871979-80-5 is a valid CAS Registry Number.

Divergent total synthesis of the tricyclic marine alkaloids lepadiformine, fasicularin, and isomers of polycitorols by reagent-controlled diastereoselective reductive amination

In, Jinkyung,Lee, Seokwoo,Kwon, Yongseok,Kim, Sanghee

supporting information, p. 17433 - 17442 (2015/02/19)

We describe a flexible and divergent route to the pyrrolo-/pyrido[1,2-j]quinoline frameworks of tricyclic marine alkaloids via a common intermediate formed by the ester-enolate Claisen rearrangement of a cyclic amino acid allylic ester. We have synthesize

Formal total synthesis of (-)-lepadiformine

Lee, Minhee,Lee, Taeho,Kim, Eun-Young,Ko, Hyojin,Kim, Deukjoon,Kim, Sanghee

, p. 745 - 748 (2007/10/03)

A stereocontrolled approach to the preparation of the Weinreb intermediate 3 has been developed. The important features of this approach are the creation of stereogenic centers through a cyclic amino acid ester-enolate Claisen rearrangement and the use of
