Check Digit Verification of cas no

The CAS Registry Mumber 3199-83-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,9 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3199-83:
(6*3)+(5*1)+(4*9)+(3*9)+(2*8)+(1*3)=105
105 % 10 = 5
So 3199-83-5 is a valid CAS Registry Number.

Dynamic kinetic resolution-asymmetric transfer hydrogenation of 1-aryl-substituted cyclic ketones

Alcock, Nathaniel J.,Mann, Inderjit,Peach, Philip,Wills, Martin

, p. 2485 - 2490 (2007/10/03)

A range of 1-aryl-2-tetranols, and 1-phenyl-2-indanol, have been generated in high yield and enantiomeric excess from the corresponding racemic ketones, via a dynamic kinetic resolution-transfer hydrogenation process, using Ru(II)-TsDPEN in formic acid/triethylamine (5:2). This provides a potential entry to an asymmetric total synthesis of benzazepines such as Sch 39166.
