23740-80-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 23740-80-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,7,4 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 23740-80:
(7*2)+(6*3)+(5*7)+(4*4)+(3*0)+(2*8)+(1*0)=99
99 % 10 = 9
So 23740-80-9 is a valid CAS Registry Number.

IMPROVED SYNTHESIS OF DIHYDROISOQUINOLINE REISSERT COMPOUNDS
Jackson, Yvette A.,Stephenson, E. Kyle,Cava, Michael P.
, p. 1047 - 1050 (2007/10/02)
Conversion of a series of 3,4-dihydroisoquinolines to their corresponding Reissert compounds was improved significantly over the usual reaction conditions by buffering the reaction medium at pH 8.
