Check Digit Verification of cas no
The CAS Registry Mumber 137219-86-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,2,1 and 9 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 137219-86:
(8*1)+(7*3)+(6*7)+(5*2)+(4*1)+(3*9)+(2*8)+(1*6)=134
134 % 10 = 4
So 137219-86-4 is a valid CAS Registry Number.

Process research on the asymmetric hydrogenation of a benzophenone for developing the manufacturing process of the squalene synthase inhibitor TAK-475

A practical synthetic method for the synthesis of the chiral benzhydrol 8, which is the key intermediate of the squalene synthase inhibitor TAK-475 (1), has been developed. The method, via asymmetric hydrogenation of the benzophenone 7, employed Noyori's ruthenium precatalyst of the type [RuCl 2(diphosphine)(diamine). We focused on tuning of the chiral diphosphine, and have discovered a novel ligand, DADMP-BINAP (18c), for the catalyst that has allowed reduction of the operating pressure in the asymmetric hydrogenation. The precatalyst containing 18c performed effectively at low hydrogen pressure (1 MPa) with sufficient enantioselectivity, and the result enabled us to successfully obtain enantiomerically pure 8 on a multikilogram scale.
