Check Digit Verification of cas no
The CAS Registry Mumber 902131-33-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,2,1,3 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 902131-33:
(8*9)+(7*0)+(6*2)+(5*1)+(4*3)+(3*1)+(2*3)+(1*3)=113
113 % 10 = 3
So 902131-33-3 is a valid CAS Registry Number.

Synthesis of 8-substituted-6-phenyl-6,7,8,9-tetrahydro-3H-pyrazolo[4,3-f]isoquinolines using Pictet-Spengler and Bischler-Napieralski cyclisation methods

In the following communication we report routes for the synthesis of a set of 8-substituted-6-phenyl-6,7,8,9-tetrahydro-3H-pyrazolo[4,3-f]isoquinolines. Pictet-Spengler and Bischler-Napieralski methodologies were employed on the relevant indazole precursors and the merits of the two cyclisation reactions for preparing these structures were assessed.
