Check Digit Verification of cas no

The CAS Registry Mumber 1098215-41-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,8,2,1 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1098215-41:
(9*1)+(8*0)+(7*9)+(6*8)+(5*2)+(4*1)+(3*5)+(2*4)+(1*1)=158
158 % 10 = 8
So 1098215-41-8 is a valid CAS Registry Number.

The Ugi reaction with CF3-carbonyl compounds: effective synthesis of α-trifluoromethyl amino acid derivatives

Gulevich, Anton V.,Shevchenko, Nikolay E.,Balenkova, Elisabeth S.,R?schenthaler, Gerd-Volker,Nenajdenko, Valentine G.

experimental part, p. 11706 - 11712 (2009/04/06)

The Ugi reaction with CF3-carbonyl compounds is described in detail. The method is efficient for the multicomponent preparation of α-trifluoromethyl (Tfm) amino acids, α-Tfm containing dipeptides, and iminodicarboxylic acids. In addition, the first protected CF3-opine derivative was prepared. The scope, limitations, and stereochemistry of the approach are discussed.
