Check Digit Verification of cas no

The CAS Registry Mumber 1298088-82-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,8,0,8 and 8 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1298088-82:
(9*1)+(8*2)+(7*9)+(6*8)+(5*0)+(4*8)+(3*8)+(2*8)+(1*2)=210
210 % 10 = 0
So 1298088-82-0 is a valid CAS Registry Number.

Silicon-(thio)urea Lewis acid catalysis

Hrdina, Radim,Mueller, Christian E.,Wende, Raffael C.,Lippert, Katharina M.,Benassi, Mario,Spengler, Bernhard,Schreiner, Peter R.

supporting information; experimental part, p. 7624 - 7627 (2011/06/26)

We present a new class of catalysts based on the combination of N,N′-diaryl(thio)ureas and weak silicon Lewis acids (e.g., SiCl 4). Such silicon-(thio)urea catalysts effectively catalyze the stereospecific rearrangement of epoxides to quaternary carbaldehydes.
