Check Digit Verification of cas no

The CAS Registry Mumber 99195-96-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,1,9 and 5 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 99195-96:
(7*9)+(6*9)+(5*1)+(4*9)+(3*5)+(2*9)+(1*6)=197
197 % 10 = 7
So 99195-96-7 is a valid CAS Registry Number.

Highly Selective Hydrogenation of C═C Bonds Catalyzed by a Rhodium Hydride

Gu, Yiting,Lisnyak, Vladislav G.,Norton, Jack R.,Salahi, Farbod,Snyder, Scott A.,Zhou, Zhiyao

, p. 9657 - 9663 (2021)

Under mild conditions (room temperature, 80 psi of H2) Cp*Rh(2-(2-pyridyl)phenyl)H catalyzes the selective hydrogenation of the C═C bond in α,β-unsaturated carbonyl compounds, including natural product precursors with bulky substituents in the β position and substrates possessing an array of additional functional groups. It also catalyzes the hydrogenation of many isolated double bonds. Mechanistic studies reveal that no radical intermediates are involved, and the catalyst appears to be homogeneous, thereby affording important complementarity to existing protocols for similar hydrogenation processes.
