Check Digit Verification of cas no

The CAS Registry Mumber 157430-57-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,4,3 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 157430-57:
(8*1)+(7*5)+(6*7)+(5*4)+(4*3)+(3*0)+(2*5)+(1*7)=134
134 % 10 = 4
So 157430-57-4 is a valid CAS Registry Number.

Flexible and stereoselective construction of polypropionate chains from enantiomerically pure γ-hydroxy-α,β-unsaturated sulfones

Dominguez, Esteban,Carretero, Juan C.

, p. 7557 - 7566 (1994)

Following an homologation sequence the readily available enantiomerically pure γ-hydroxy vinyl sulfone 2 has been transformed, with complete control of the stereochemistry, into γ-hydroxy vinyl sulfones of polypropionate structure. The four stereotriads have been prepared by stereoselective additions of organometallics to the vinyl sulfone moiety and by stereoselective reduction of β-hydroxyketones. In a similar way, these triads are the substrates for the stereoselective introduction of the fourth consecutive asymmetric center.
