Check Digit Verification of cas no

The CAS Registry Mumber 117709-26-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,7,0 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 117709-26:
(8*1)+(7*1)+(6*7)+(5*7)+(4*0)+(3*9)+(2*2)+(1*6)=129
129 % 10 = 9
So 117709-26-9 is a valid CAS Registry Number.

A Comprehensive Approach to (S)-(-)-2-Methyl-1-Butanol as a Convenient Precursor for Synthesis of Chiral Liquid Crystals

Kaszynski, P.,Jawdosiuk, M.

, p. 21 - 38 (2007/10/02)

The chemistry of S-(-)-2-methyl-1-butanol leading to chiral liquid crystals (CLC) and their intermediates is summarized and new facile synthetic methods are described.Efficiency of the presented methods is discussed and illustrated with syntheses of several known and new CLC as well as the corresponding chiral intermediates.The newly synthesized chiral compounds display cholestic and smectic phases.Keywords: (S)-(-)-2-methyl-1-butanol, (S)-(+)-methyl-1-butyl benzenesulfonate, chiral liquid crystals, smectic C
