Check Digit Verification of cas no
The CAS Registry Mumber 346579-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,6,5,7 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 346579-89:
(8*3)+(7*4)+(6*6)+(5*5)+(4*7)+(3*9)+(2*8)+(1*9)=193
193 % 10 = 3
So 346579-89-3 is a valid CAS Registry Number.

Acylation of amino acids with furancarboxylic acid chlorides
Lapina,Pevzner
, p. 1479 - 1483 (2007/10/03)
Acylation of aromatic amino acids with furancarboxylic acid chlorides effectively proceeds in water-acetone medium at pH 8-9. Aliphatic amino acids are acylated at higher pH values, but under these conditions hydrolysis of acid chlorides becomes the main
