205-27-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 205-27-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,0 and 5 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 205-27:
(5*2)+(4*0)+(3*5)+(2*2)+(1*7)=36
36 % 10 = 6
So 205-27-6 is a valid CAS Registry Number.

A Reinvestigation of Stillwell's Synthesis of 6H-Pyridocarbazoles
Bergman, Jan,Goonewardena, Harris
, p. 763 - 766 (2007/10/02)
11-Methyl-6H-pyridocarbazole (5-norellipticine) has been synthesized using a new method for the construction of the central carboxylic ring. 5-Norellipticine synthesized by this route is identical with a product earlier reported.
