Check Digit Verification of cas no

The CAS Registry Mumber 159029-63-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,0,2 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 159029-63:
(8*1)+(7*5)+(6*9)+(5*0)+(4*2)+(3*9)+(2*6)+(1*3)=147
147 % 10 = 7
So 159029-63-7 is a valid CAS Registry Number.

Synthesis, resolution and absolute configuration determination of (S)- and (R)-4-formyl-5-hydroxyparacyclophane and its application in the asymmetric synthesis of α-amino acids

Antonov, Dmitri Yu.,Belokon, Yuri N.,Ikonnikov, Nikolai S.,Orlova, Svetlana A.,Pisarevsky, Aleksander P.,et al.

, p. 1873 - 1880 (2007/10/02)

Racemic (R,S)-4-formyl-5-hydroxyparacyclophane (FHPC) was resolved into enantiomers via its Schiff's base with (S)- and (R)-α-phenylethylamine (α-PEAM) and its absolute configuration was determined by an X-ray diffraction structural study.Scalemic FHPC or its derivatives can be used as chiral auxiliaries for the asymmetric synthesis of β-hydroxy-α-amino acids and α-methylphenylalanine with ees ranging mostly from 45 to 98percent.
