116120-18-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116120-18-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,1,2 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 116120-18:
(8*1)+(7*1)+(6*6)+(5*1)+(4*2)+(3*0)+(2*1)+(1*8)=74
74 % 10 = 4
So 116120-18-4 is a valid CAS Registry Number.

INTRAMOLECULAR ADDITION OF AMINES TO CHIRAL VINYL SULFOXIDES, TOTAL SYNTHESIS OF (R)-(+)-CANADINE
Pyne, Stephen G.
, p. 4737 - 4740 (2007/10/02)
The intramolecular conjugate addition of an amine to the chiral vinyl sulfoxides 3 and 4 to give chiral isoquinolines 5 and 6 is reported.Isoquinoline 5 is converted to (R)-(+)-Canadine via an intramolecular Pummerer reaction.
