Check Digit Verification of cas no

The CAS Registry Mumber 1260086-02-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,0,0,8 and 6 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1260086-02:
(9*1)+(8*2)+(7*6)+(6*0)+(5*0)+(4*8)+(3*6)+(2*0)+(1*2)=119
119 % 10 = 9
So 1260086-02-9 is a valid CAS Registry Number.

First general route to substituted α-arylamino-α′ chloropropan-2-ones by oxidation of N-protected aminohalohydrins: The importance of disrupting hydrogen bond networks

Pace, Vittorio,Cabrera, Alvaro Cortes,Fernandez, Maria,Sinisterra, Jose V.,Alcantara, Andres R.

, p. 3545 - 3555 (2010)

The presence of a network of intra- and intermolecular hydrogen bonds in β-arylamino alcohols, confirmed by both IR spectroscopy and computer modeling, inhibits their oxidation to the corresponding α-amino ketones. A straightforward protocol, including highly regioselective protection (as carbamates) and subsequent oxidation with Dess-Martin periodinane, affords near quantitative yields of the desired N-protected ketones, which upon mild treatment with iodotrimethylsilane leads to a series of differently functionalized α-arylamino-α′-chloro ketones. Georg Thieme Verlag Stuttgart.
