Calculate Digit Verification of CAS Registry Number 78651-83:
(7*7)+(6*8)+(5*6)+(4*5)+(3*1)+(2*8)+(1*3)=169
169 % 10 = 9
So 78651-83-9 is a valid CAS Registry Number.

Synthesis of 14-hydroxytetra- and 15-hydroxypentadecanoic acids

Zakharkin, L. I.,Guseva V. V.,Pryanishnikov A. P.

, p. 658 - 661 (2007/10/02)

14-Hydroxytetradecanoic and 15-hydroxypentadecanoic acids were synthesized from 1,10-decanedicarboxylic and 1,11-undecanedicarboxylic acids.The diesters of the latter were reduced to the diols, from which the chlorohydrins were obtained by reaction with hydrogen chloride.The use of these chlorohydrins in the sodiomalonic synthesis leads to the hydroxy carboxylic acids.
