Check Digit Verification of cas no

The CAS Registry Mumber 1449291-35-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,9,2,9 and 1 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1449291-35:
(9*1)+(8*4)+(7*4)+(6*9)+(5*2)+(4*9)+(3*1)+(2*3)+(1*5)=183
183 % 10 = 3
So 1449291-35-3 is a valid CAS Registry Number.

Kinetic resolution of tertiary alcohols: Highly enantioselective access to 3-hydroxy-3-substituted oxindoles

Lu, Shenci,Poh, Si Bei,Siau, Woon-Yew,Zhao, Yu

supporting information, p. 1731 - 1734 (2013/04/10)

Enantioselective: The first highly enantioselective kinetic resolution of 3-hydroxy-3-substituted oxindoles has been developed through oxidative esterification catalyzed by a N-heterocyclic carbene (see picture). This method uses a simple procedure and provides 3-hydroxy-oxindoles with various substituents at the 3-position in excellent enantiopurity. S=selectivity. Copyright
