Check Digit Verification of cas no
The CAS Registry Mumber 90052-39-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,0,5 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 90052-39:
(7*9)+(6*0)+(5*0)+(4*5)+(3*2)+(2*3)+(1*9)=104
104 % 10 = 4
So 90052-39-4 is a valid CAS Registry Number.

Evaluation of bifunctional chiral phosphine oxide catalysts for the asymmetric hydrosilylation of ketimines
Warner, Christopher J.A.,Berry, Sian S.,Jones, Simon
, (2019/11/11)
A series of bifunctional phosphine oxides have been prepared and evaluated as catalysts for the trichlorosilane mediated asymmetric hydrosilylation of ketimines. bis-Phosphine oxides, hydroxy-phosphine oxides, and biaryl phosphine oxides all demonstrated good catalytic activity, but poor to moderate enantioselectivity. A bis-P-chiral phosphine oxide displayed the highest enantioselectivity of 60%.
