Check Digit Verification of cas no

The CAS Registry Mumber 1062550-63-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,6,2,5,5 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1062550-63:
(9*1)+(8*0)+(7*6)+(6*2)+(5*5)+(4*5)+(3*0)+(2*6)+(1*3)=123
123 % 10 = 3
So 1062550-63-3 is a valid CAS Registry Number.

Br?nsted acid catalyzed asymmetric reduction of 2- and 2,9-substituted 1,10-phenanthrolines

Metallinos, Costa,Barrett, Fred B.,Xu, Shufen

, p. 720 - 724 (2008/12/22)

Several 2- and 2,9-substituted 1,10-phenanthrolines are reduced asymmetrically for the first time using a Hantzsch dihydropyridine in the presence of BINOL-derived phosphoric acid catalysts. The best results are obtained with phenanthrolines bearing unbranched or nitrogen-containing alkyl groups in the 2- or 2,9-positions, which afford chiral octahydrophenanthrolines in a range of yields (40-88%) and good to excellent levels of enantiomeric purity (78-99% ee).
