Check Digit Verification of cas no

The CAS Registry Mumber 1202242-84-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,2,2,4 and 2 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1202242-84:
(9*1)+(8*2)+(7*0)+(6*2)+(5*2)+(4*4)+(3*2)+(2*8)+(1*4)=89
89 % 10 = 9
So 1202242-84-9 is a valid CAS Registry Number.

Synthesis of novel C2-symmetric chiral crown ethers and investigation of their enantiomeric recognition properties

Turgut, Yilmaz,Aral, Tarik,Hosgoren, Halil

experimental part, p. 2293 - 2298 (2010/03/24)

A series of new C2-symmetric chiral aza crown ether macrocycles 1-4 have been synthesized from (S)-3-aryloxy-1,2-propanediol and (S)-1,2-propanediol for the enantiomeric recognition of amino acid ester derivatives. These new macrocycles have be
