133964-03-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133964-03-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,9,6 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 133964-03:
(8*1)+(7*3)+(6*3)+(5*9)+(4*6)+(3*4)+(2*0)+(1*3)=131
131 % 10 = 1
So 133964-03-1 is a valid CAS Registry Number.

THE SYNTHESIS OF NOVEL NITROGEN-CONTAINING MACROCYCLES FROM ISOXAZOLINE INTERMEDIATES
Wentland, Mark P.
, p. 1477 - 1478 (2007/10/02)
Novel macrocyclic isoxazolobenzazonine derivatives (4) have been prepared via 1,3-dipolar cycloaddition of an aryl nitrile oxide to a bridge polycyclic enamine followed by a quaternization sequence.
