135365-20-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135365-20-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,3,6 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 135365-20:
(8*1)+(7*3)+(6*5)+(5*3)+(4*6)+(3*5)+(2*2)+(1*0)=117
117 % 10 = 7
So 135365-20-7 is a valid CAS Registry Number.

Use of the N-formyliminium ion cyclization for the synthesis of 3-aryl-1,2,3,4-tetrahydroisoquinolines
Maryanoff,Rebarchak
, p. 1245 - 1248 (2007/10/02)
Classical cyclization procedures for the synthesis of 3-arylisoquinolines are fraught with complications. Here, we present the application of an N-acyliminium cyclization to such target molecules. N(1,2-diarylethyl)formamides 1, 4a-4d, and 4f were cyclize
