662168-53-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 662168-53-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,2,1,6 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 662168-53:
(8*6)+(7*6)+(6*2)+(5*1)+(4*6)+(3*8)+(2*5)+(1*3)=168
168 % 10 = 8
So 662168-53-8 is a valid CAS Registry Number.

Synthesis of Amphidinolide T1 via Catalytic, Stereoselective Macrocyclization
Colby, Elizabeth A.,O'Brien, Karen C.,Jamison, Timothy F.
, p. 998 - 999 (2004)
Two nickel-catalyzed reductive coupling reactions of alkynes were instrumental in a modular, stereoselective synthesis of amphidinolide T1 (1). The C13-C21 fragment was prepared from two simple starting materials that were joined in a catalytic alkyne-epo
