Check Digit Verification of cas no

The CAS Registry Mumber 1258208-40-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,2,0 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1258208-40:
(9*1)+(8*2)+(7*5)+(6*8)+(5*2)+(4*0)+(3*8)+(2*4)+(1*0)=150
150 % 10 = 0
So 1258208-40-0 is a valid CAS Registry Number.

Kinetic resolution of homoaldols via catalytic asymmetric transacetalization

Coric, Ilija,Mueller, Steffen,List, Benjamin

supporting information; experimental part, p. 17370 - 17373 (2011/02/23)

The highly enantioselective kinetic resolution of homoaldols via a transacetalization reaction has been achieved. A novel phosphoric acid, STRIP, based on a spirocyclic 1,1′-spirobiindane backbone was designed and identified as a superior catalyst for this transformation. Remarkably, both secondary and tertiary homoaldols gave equally excellent results.
