Check Digit Verification of cas no
The CAS Registry Mumber 38664-16-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,6,6 and 4 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 38664-16:
(7*3)+(6*8)+(5*6)+(4*6)+(3*4)+(2*1)+(1*6)=143
143 % 10 = 3
So 38664-16-3 is a valid CAS Registry Number.

Reaction of some diketones with 5-aminolevulinic acid in acid solution
Butler,George
, p. 7017 - 7026 (2007/10/02)
Some 2,4-diketones react with 5-aminolevulinic acid in acid solution to form pyrroles. There are two modes of cyclisation, one leading to the Knorr and the other to the Fischer-Fink product. By a consideration of the products obtained from pentane-, hexane-, 3-methylpentane-, 3-isopropylpentane-, 3,3-dimethylpentane-, 1,1,1-trifluoropentane- 1,1,1,5,5,5-hexafluoro- pentane-2,4-dione and ethyl acetoacetate some generalisations concerning the formation of Knorr and Fischer-Fink products have been made. The reactions of 5-methyl-5-aminolevulinic acid with pentane- and 3-methylpentane-2,4-dione have also been examined. The relevance of these studies to the cyclic dimerisation of 5-aminolevulinic acid is discussed briefly.
