Check Digit Verification of cas no

The CAS Registry Mumber 1033725-64-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,3,7,2 and 5 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1033725-64:
(9*1)+(8*0)+(7*3)+(6*3)+(5*7)+(4*2)+(3*5)+(2*6)+(1*4)=122
122 % 10 = 2
So 1033725-64-2 is a valid CAS Registry Number.

Sulfoxide-directed stereocontrolled access to 2H-chromans: Total synthesis of the (S,R,R,R)-enantiomer of the antihypertensive drug nebivolol

Carreno, M. Carmen,Hernandez-Torres, Gloria,Urbano, Antonio,Colobert, Francoise

, p. 2035 - 2038 (2008)

A homochiral sulfoxide-directed reductive deoxygenation of 2-(p-tolylsulfinyl)methyl-2-chromanols allows the stereoselective formation of 2H-chromans with up to 95:5 diastereoisomeric ratio. This new methodology was applied in a short and convergent enantioselective synthesis of the (S,R,R,R)-enantiomer of the antihypertensive drug Nebivolol. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.
