27798-66-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 27798-66-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,7,9 and 8 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 27798-66:
(7*2)+(6*7)+(5*7)+(4*9)+(3*8)+(2*6)+(1*6)=169
169 % 10 = 9
So 27798-66-9 is a valid CAS Registry Number.

A few 6H-pyrido[4,3-b]carbazoles were prepared for cytotoxicity testing in cultures of human lung cancer cells. Methyl 6-methoxyindoleacetate 13, prepared by reduction of methyl 4-(2-nitro-5-methoxyphenyl)-3-oxobutyrate 11, was condensed with 3-acetylpyri
