144367-94-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144367-94-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,3,6 and 7 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 144367-94:
(8*1)+(7*4)+(6*4)+(5*3)+(4*6)+(3*7)+(2*9)+(1*4)=142
142 % 10 = 2
So 144367-94-2 is a valid CAS Registry Number.

Cobalt-mediated aryl radical cyclisations: A formal synthesis of physovenine
Clark, Andrew J.,Jones, Keith
, p. 6875 - 6882 (1992)
A synthesis of the tetrahydrofuro[2,3-b]indole (3) in 6 steps from 4-methoxyaniline involving a key cobalt-mediated radical cyclisation is presented. This heterocycle is a known, late intermediate in the synthesis of the alkaloid physovenine (2).
