Check Digit Verification of cas no

The CAS Registry Mumber 108142-74-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,1,4 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 108142-74:
(8*1)+(7*0)+(6*8)+(5*1)+(4*4)+(3*2)+(2*7)+(1*4)=101
101 % 10 = 1
So 108142-74-1 is a valid CAS Registry Number.

Absolute configuration and enantiomeric purity of celiprolol

Hofer,Schlogl

, p. 1157 - 1161 (2007/10/02)

The absolute configuration of (+)-celiprolol ([α]D = +6.3° in CHCl3) was established by a 9-step synthesis via the (+) (R)-acetonide of (R)-glyceraldehyde. This result was confirmed by the Cupra-A CD-spectra of the isopropyl and hydroxyl analogs. The enantiomeric purity was determined by NMR analysis of the diastereomeric amide esters obtained by reaction of celiprolol with 2 mol of α-methoxy-α-trifluormethylphenylacetic acid chloride (Mosher's reagent).
