Check Digit Verification of cas no

The CAS Registry Mumber 57025-62-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,0,2 and 5 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 57025-62:
(7*5)+(6*7)+(5*0)+(4*2)+(3*5)+(2*6)+(1*2)=114
114 % 10 = 4
So 57025-62-4 is a valid CAS Registry Number.

The highly enantioselective transformation of silylketenes into α-silylthioesters catalysed by cinchona alkaloids

Blake, Alexander J.,Friend, Christopher L.,Outram, Robert J.,Simpkins, Nigel S.,Whitehead, Andrew J.

, p. 2877 - 2881 (2007/10/03)

The reaction of silylketenes with thiophenol, mediated by cinchona alkaloid catalysts, proceeds to give α-silylthioester products in good chemical yield and with enantiomeric excess values in the range 79-93%. The absolute configuration of one of the thioester products was determined by X-ray diffraction.
