Check Digit Verification of cas no

The CAS Registry Mumber 517920-45-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,7,9,2 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 517920-45:
(8*5)+(7*1)+(6*7)+(5*9)+(4*2)+(3*0)+(2*4)+(1*5)=155
155 % 10 = 5
So 517920-45-5 is a valid CAS Registry Number.

Diastereoselective addition of chlorotitanium enolate of N-acyl thiazolidinethione to O-methyl oximes: A novel, stereoselective synthesis of α,β-disubstituted β-amino carbonyl compounds via chiral auxiliary mediated azetine formation

Ambhaikar, Narendra B.,Snyder, James P.,Liotta, Dennis C.

, p. 3690 - 3691 (2003)

We have discovered a novel and highly diastereoselective synthesis of azetinyl thiazolidine-2-thiones that utilizes additions of the chlorotitanium enolates of N-acyl thiazolidin-2-thiones to O-methyl aldoximes. The "anti" azetines can be subsequently con
