Check Digit Verification of cas no

The CAS Registry Mumber 205526-59-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,5,2 and 6 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 205526-59:
(8*2)+(7*0)+(6*5)+(5*5)+(4*2)+(3*6)+(2*5)+(1*9)=116
116 % 10 = 6
So 205526-59-6 is a valid CAS Registry Number.

Reductive and oxidative transformations of the N-(cyanomethyl)oxazolidine system to expand the chiral pool of piperidines

Francois, David,Poupon, Erwan,Kunesch, Nicole,Husson, Henri-Philippe

, p. 4823 - 4829 (2007/10/03)

Two new reactions have been exploited to modify piperidine scaffolds containing the chiral, non-racemic N-(cyanomethyl)oxazolidine system. A Raney nickel mediated decyanation was studied first, followed by an oxidative process using potassium permanganate
