121440-79-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121440-79-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,4,4 and 0 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 121440-79:
(8*1)+(7*2)+(6*1)+(5*4)+(4*4)+(3*0)+(2*7)+(1*9)=87
87 % 10 = 7
So 121440-79-7 is a valid CAS Registry Number.

Asymmetric Synthesis of (3R,5R)- and (3S,5S)-2,6-Dimethylheptane-3,5-diol, useful C2 Chiral Auxiliaries
Jacoby, C.,Braekman, J.C.,Daloze, D.
, p. 753 - 756 (1995)
(R,R)- and (S,S)-2,6-Dimethylheptane-3,5-diol, which are useful C2 chiral auxiliaries, have been both synthesized in high optical purity from 2,6-dimethylheptane-3,5-dione, by using as key step a Sharpless kinetic resolution.
