57291-88-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57291-88-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,2,9 and 1 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 57291-88:
(7*5)+(6*7)+(5*2)+(4*9)+(3*1)+(2*8)+(1*8)=150
150 % 10 = 0
So 57291-88-0 is a valid CAS Registry Number.

This paper describes a new artificial cyclase, optically pure 3-o-fluorobenzyloxy-2-hydroxy-2′-(p-methoxybemzyl)-1,1′-binaphthyl·SnCl4, which is effective for the enantioselective cyclization of 2-(polyprenyl)phenol derivatives to afford polycy
