547652-91-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 547652-91-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,7,6,5 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 547652-91:
(8*5)+(7*4)+(6*7)+(5*6)+(4*5)+(3*2)+(2*9)+(1*1)=185
185 % 10 = 5
So 547652-91-5 is a valid CAS Registry Number.

A short three-component synthesis of tricyclic compounds
Hilt, Gerhard,Korn, Tobias J.,Smolko, Konstantin I.
, p. 241 - 243 (2007/10/03)
A facile reaction sequence, consisting of a palladium-catalyzed Sonogashira coupling, a cobalt-catalyzed Diels - Alder reaction and a subsequent cyclization initiated by a bromine-lithium exchange reaction, allows a three-component synthesis of tricyclic
