Check Digit Verification of cas no

The CAS Registry Mumber 86839-41-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,8,3 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 86839-41:
(7*8)+(6*6)+(5*8)+(4*3)+(3*9)+(2*4)+(1*1)=180
180 % 10 = 0
So 86839-41-0 is a valid CAS Registry Number.

Heterocyclic 8?-Systems, 15. Investigations on Indole 2,3-Oxides: Sythesis of 3-Hydroxyindoles via Intramolecular Wittig-Rearrangement of 1,2-Dihydro-4H-3,1-benzoxazines

Schmidt, Richard R.,Beitzke, Bernhard

, p. 2115 - 2135 (2007/10/02)

Investigations to trap indole 2,3-oxides 11 by base catalyzed ring contraction of 4H-3,1-benzoxazines 3 led in the system KNH2/NH3 to 3-hydroxy-3H-indoles 7.The N-methylbenzoxazinium salts 15, obtained from 3 and FSO3CH3, yielded with ethoxide under kinet
