117828-34-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117828-34-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,8,2 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 117828-34:
(8*1)+(7*1)+(6*7)+(5*8)+(4*2)+(3*8)+(2*3)+(1*4)=139
139 % 10 = 9
So 117828-34-9 is a valid CAS Registry Number.

A Synthetic Approach to Rocaglamide via Reductive Cyclization of δ-Keto Nitriles
Kraus, George A.,Sy, James O.
, p. 77 - 83 (2007/10/02)
The anticancer agent rocaglamide contains a novel bicyclooctanol structure.The approach to this molecule involved the preparation of a hydroxy ketone intermediate via a samarium-mediated cyclization.This ketone was then converted into an excellent
