Check Digit Verification of cas no

The CAS Registry Mumber 135748-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,7,4 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 135748-89:
(8*1)+(7*3)+(6*5)+(5*7)+(4*4)+(3*8)+(2*8)+(1*9)=159
159 % 10 = 9
So 135748-89-9 is a valid CAS Registry Number.

Synthesis of long-chain picolinic derivatives

Faivre, V.,Roizard, D.,Brembilla, A.,Lochon, P.

, p. 278 - 285 (2007/10/02)

5-Hydroxypicoline is the common starting product for the reported synthesis of new picolinic derivatives with various oxidation degrees (methyl, N-oxide, alcohol, aldehyde, acid) and with their 5-position substituted by a linear alkoxy chain with n carbon atoms (n = 3,5,7,10,12,15 and 18).The parent carboxylic acids are then converted into activated esters which can be used as substrates in micellar catalysis studies. --- Key words: 5-hydroxypicoline / O-alkylation / 5-alkoxypicolinic derivatives
