Check Digit Verification of cas no

The CAS Registry Mumber 61425-45-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,4,2 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 61425-45:
(7*6)+(6*1)+(5*4)+(4*2)+(3*5)+(2*4)+(1*5)=104
104 % 10 = 4
So 61425-45-4 is a valid CAS Registry Number.

Bronsted acid catalyzed asymmetric reduction of ketones and acyl silanes using chiral anti -pentane-2,4-diol

Matsuo, Jun-Ichi,Hattori, Yu,Ishibashi, Hiroyuki

supporting information; experimental part, p. 2294 - 2297 (2010/08/05)

Ketones and acyl silanes were reduced to the corresponding alcohols by a simple procedure employing anti-1,3-diol and a catalytic amount (5 mol %) of 2,4-dinitrobenzenesulfonic acid in benzene at reflux. Asymmetric induction reached up to >99% ee when a chiral pentane-2,4-diol of 97% ee was used.
