133527-98-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133527-98-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,5,2 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 133527-98:
(8*1)+(7*3)+(6*3)+(5*5)+(4*2)+(3*7)+(2*9)+(1*8)=127
127 % 10 = 7
So 133527-98-7 is a valid CAS Registry Number.

SYNTHESIS OF ISOQUINOQUINAZOLINES BY CYCLOADDITION REACTION
Kanmacher, Isabelle,Stambach, Jean-Francois,Jung, Louis
, p. 2131 - 2138 (2007/10/02)
The cycloaddition reaction of 3,4-dihydroisoquinolinium salts (2c,d) with 2-aminobenzaldehydes (1a,b) was a convenient way to obtain 5,6,13,13a-tetrahydro-8H-isoquinoquinazolinium salts (3a-d).The reduction, transposition and oxidation of these com
