Check Digit Verification of cas no

The CAS Registry Mumber 57662-91-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,6,6 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 57662-91:
(7*5)+(6*7)+(5*6)+(4*6)+(3*2)+(2*9)+(1*1)=156
156 % 10 = 6
So 57662-91-6 is a valid CAS Registry Number.

Hydrogenation of sulfoxides to sulfides under mild conditions using ruthenium nanoparticle catalysts

Mitsudome, Takato,Takahashi, Yusuke,Mizugaki, Tomoo,Jitsukawa, Koichiro,Kaneda, Kiyotomi

, p. 8348 - 8351 (2014)

The first demonstration of the hydrogenation of sulfoxides under atmospheric H2 pressure is reported. The highly efficient reaction is facilitated by a heterogeneous Ru nanoparticle catalyst. The mild reaction conditions enable the selective hydrogenation of a wide range of functionalized sulfoxides to the corresponding sulfides. The high redox ability of RuO x nanoparticles plays a key role in the hydrogenation.
