Check Digit Verification of cas no

The CAS Registry Mumber 92818-05-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,8,1 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 92818-05:
(7*9)+(6*2)+(5*8)+(4*1)+(3*8)+(2*0)+(1*5)=148
148 % 10 = 8
So 92818-05-8 is a valid CAS Registry Number.

Mutual Kinetic Resolution of Racemic 3,4-Dihydro-3-methyl-2H-[1,4]benzoxazines with Acyl Chlorides of Racemic O-Phenyllactic Acids and DFT Modelling of Transition States

The effect of the electronic nature of the para substituent on the aromatic ring of 2-aryloxypropionyl chlorides on the stereochemical outcome of the acylation of 3,4-dihydro-3-methyl-2H-[1,4]benzoxazine and its 7,8-difluoro-containing analogue has been studied. The geometries of the diastereoisomeric transition states and the corresponding Gibbs free enthalpies of activation were determined through DFT calculations at the COSMO-CH2Cl2-B3LYP-D3-gCP/def2-TZVP (or def2-SVP)//B3LYP-D3-gCP/def2-SVP level of theory. It has been found that a low-cost quantum chemical calculation at a chosen level of theory describes well the quantitative dependence of the selectivity of acylation on the structures of the reagents. The obtained results indicate that aromatic interactions between the reagents play a significant role in the process of stereodifferentiation, ensuring high selectivity of the acylation of benzoxazines with 2-aryloxyacyl chlorides.
