93464-60-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93464-60-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,4,6 and 4 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 93464-60:
(7*9)+(6*3)+(5*4)+(4*6)+(3*4)+(2*6)+(1*0)=149
149 % 10 = 9
So 93464-60-9 is a valid CAS Registry Number.

The benzisoquinolines 2a and 2b were prepared by two ways from the tetrasubstituted naphthalene 1a.A second-order Beckmann rearrangement is described which leads to the salt 5, which is demetylated.A three-step procedure leads from 1a to the homologous naphthazepine 9.
