Check Digit Verification of cas no

The CAS Registry Mumber 352238-75-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,2,2,3 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 352238-75:
(8*3)+(7*5)+(6*2)+(5*2)+(4*3)+(3*8)+(2*7)+(1*5)=136
136 % 10 = 6
So 352238-75-6 is a valid CAS Registry Number.

A divergent approach to benzylisoquinoline-type and oxoaporphine alkaloids via regioselective direct ring metalation of alkoxy isoquinolines

Melzer, Benedikt,Bracher, Franz

, p. 7664 - 7672 (2015/07/15)

Methoxy- and benzyloxy-substituted isoquinolines are regioselectively metalated at C-1 with the Knochel-Hauser base, subsequent trapping with aromatic aldehydes gives aryl(isoquinolin-1-yl)carbinols as building blocks for divergent syntheses of different types of benzylisoquinoline alkaloids. Photochemical cyclization of ortho-bromo analogues under reductive conditions gives oxoaporphine alkaloids. Nine benzylisoquinoline alkaloids and two oxoaporphine alkaloids were obtained in two or three steps from appropriate isoquinolines.
