Check Digit Verification of cas no

The CAS Registry Mumber 119123-53-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,1,2 and 3 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 119123-53:
(8*1)+(7*1)+(6*9)+(5*1)+(4*2)+(3*3)+(2*5)+(1*3)=104
104 % 10 = 4
So 119123-53-4 is a valid CAS Registry Number.

A New Site Selective Synthesis of Benzoin Esters. Synthesis of Symmetrically and Unsymmetrically Substituted Benzils

Armesto, Diego,Horspool, William M.,Ortiz, Maria J.,Perez-Ossorio, Rafael

, p. 799 - 801 (2007/10/02)

A series of novel benzoin esters has been obtained in high yield, in a site selective synthesis, by the acid hydrolysis of a series of 4-benzoyloxy-2-azabuta-1,3-dienes.The oxidation of the benzoin esters allows the preparation of symmetrically and unsymmetrically substituted benzils by a route that is superior, in some cases, to those previously reported.
