Check Digit Verification of cas no

The CAS Registry Mumber 1019203-00-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,9,2,0 and 3 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1019203-00:
(9*1)+(8*0)+(7*1)+(6*9)+(5*2)+(4*0)+(3*3)+(2*0)+(1*0)=89
89 % 10 = 9
So 1019203-00-9 is a valid CAS Registry Number.

Novel C2-symmetric macrocycles bearing diamide-diester groups: Synthesis and enantiomeric recognition for primary alkyl ammonium salts

Sunkur, Murat,Baris, Deniz,Hosgoren, Halil,Togrul, Mahmut

, p. 2570 - 2575 (2008)

(Chemical Equation Presented) We synthesized a series of novel macrocycles with diamide-diester groups (S,S)-1, (S,S)-2, (S,S)-3, and (R,R)-1, derived from dimethyloxalate and amino alcohols by high dilution technique, and evaluated enantiomeric recognition properties of these macrocycles toward primary alkyl ammonium salts by 1H NMR titration. Taking into account the host employed, important differences were observed in the Ka values of (R)-Am and (S)-Am for (S,S)-1 and (R,R)-1 hosts, KS/KR = 5.55 and KR/KS = 3.65, ΔΔGo = 0.43 and -0.32 kJ mol-1, respectively. There seems a general tendency for the host to include the guests with the same absolute configuration.
