Check Digit Verification of cas no

The CAS Registry Mumber 5703-20-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,0 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5703-20:
(6*5)+(5*7)+(4*0)+(3*3)+(2*2)+(1*0)=78
78 % 10 = 8
So 5703-20-8 is a valid CAS Registry Number.

Amidoearbonylation of aldehydes utilizing cobalt oxide-supported gold nanoparticles as a heterogeneous catalyst

Hamasaki, Akiyuki,Liu, Xiaohao,Tokunaga, Makoto

supporting information; experimental part, p. 1292 - 1293 (2009/12/03)

Cobalt oxide-supported gold-nanoparticles-catalyzed transformation of aldehydes and their equivalents to N-acyl-α-arnino acids was achieved. The desired products were obtained in moderate to excellent yields under milder reaction conditions than previous reports employing octacarbonyldicobalt as a catalyst. Copyright
