Check Digit Verification of cas no

The CAS Registry Mumber 1258507-69-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,5,0 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1258507-69:
(9*1)+(8*2)+(7*5)+(6*8)+(5*5)+(4*0)+(3*7)+(2*6)+(1*9)=175
175 % 10 = 5
So 1258507-69-5 is a valid CAS Registry Number.

New chiral ligands: 1,4-diols prepared from (S)-1-phenylethanol

Shishkina,Sokolovskaya,Potekhin,Nelyubina,Askerov,Dem'Yanovich

experimental part, p. 1332 - 1338 (2011/01/04)

The stereochemistry of condensation of dilithiated 1-phenylethanol with various carbonyl compounds was investigated. In most cases the reaction proceeds nonstreoselectively, and only in the condensation with PhCOBu-t and 2,4-(MeO)2C6H3COPh only one of the diastereomeric diols prevailed. It was shown by XRD analysis that in the prevailing diastereomeric diol the newly formed chiral carbinol center possessed the same configuration as the initial alcohol. The synthesized diols form homochiral dimers in the crystal lattice.
