146530-34-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 146530-34-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,5,3 and 0 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 146530-34:
(8*1)+(7*4)+(6*6)+(5*5)+(4*3)+(3*0)+(2*3)+(1*4)=119
119 % 10 = 9
So 146530-34-9 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
