153093-73-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 153093-73-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,0,9 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 153093-73:
(8*1)+(7*5)+(6*3)+(5*0)+(4*9)+(3*3)+(2*7)+(1*3)=123
123 % 10 = 3
So 153093-73-3 is a valid CAS Registry Number.

Synthesis of 11-Membered Enediyne Ketones by the Intramolecular Nicholas Reaction
Maier, Martin E.,Brandstetter, Tilmann
, p. 1009 - 1016 (2007/10/02)
An efficient route to 11-membered enediyne ketones 13 and 22 was developed.This route is based on an intramolecular Nicholas reaction of 11 and 20, respectively.In the course of the preparation of the cyclization substrates 11 and 20, it was important to
