The CAS Registry Mumber 140886-24-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,8,8 and 6 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 140886-24:
(8*1)+(7*4)+(6*0)+(5*8)+(4*8)+(3*6)+(2*2)+(1*4)=134
134 % 10 = 4
So 140886-24-4 is a valid CAS Registry Number.

Remote Control of Double Bond Stereochemistry in the Wadsworth-Emmons Reaction

Lopez-Tudanca, Pedro L.,Jones, Keith,Brownbridge, Peter

, p. 533 - 534 (2007/10/02)

Wadsworth-Emmons reactions of 6-methoxytetrahydropyran-3-one 2 and 5-arylthio-6-methoxytetrahydropyran-3-one 5 - 9 have been investigated and the ratio of (E)- and (Z)-α,β-unsaturated esters formed has been shown to be affected by the presence and type of arylthio substituent.
