Check Digit Verification of cas no

The CAS Registry Mumber 174187-78-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,1,8 and 7 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 174187-78:
(8*1)+(7*7)+(6*4)+(5*1)+(4*8)+(3*7)+(2*7)+(1*8)=161
161 % 10 = 1
So 174187-78-1 is a valid CAS Registry Number.

Rhodium(I)-catalyzed enantioselective hydrogenation of substituted acrylic acids with sterically similar β,β-diaryls

Li, Yang,Dong, Kaiwu,Wang, Zheng,Ding, Kuiling

supporting information, p. 6748 - 6752 (2013/07/26)

Distinct differentiation: β,β-Disubstituted acrylic acids with sterically similar geminal diaryl groups can be hydrogenated with excellent enantioselectivities in the presence of a RhI complex formed in situ with two-component ligands, a chiral secondary phosphine oxide (SPO) and an achiral phosphine (Ph3P). The sense of asymmetric induction was found to be controlled by the substrate configuration, thus allowing access to both enantiomers of the product with the same catalyst. Copyright
