Check Digit Verification of cas no

The CAS Registry Mumber 1262121-47-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,1,2 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1262121-47:
(9*1)+(8*2)+(7*6)+(6*2)+(5*1)+(4*2)+(3*1)+(2*4)+(1*7)=110
110 % 10 = 0
So 1262121-47-0 is a valid CAS Registry Number.

A feasibility study on the synthesis of phenylephrine via ruthenium-catalyzed homogeneous asymmetric hydrogenation

McGarrity, John F.,Zanotti-Gerosa, Antonio

, p. 2479 - 2486 (2010)

We report a feasibility study on a new route to (R)-phenylephrine, based on the ruthenium-catalyzed asymmetric hydrogenation of an aminoketone precursor. The direct and fast asymmetric reduction of aminoketones or their hydrochloride salts is achievable at low catalyst loadings (molar substrate to catalyst ratio, S/C, >25,000/1, TOF up to 25,000 h-1) with high enantioselectivity (>95% ee), without the need for N-protection nor isolation of the free base prior to reaction.
