Check Digit Verification of cas no

The CAS Registry Mumber 244757-39-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,4,7,5 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 244757-39:
(8*2)+(7*4)+(6*4)+(5*7)+(4*5)+(3*7)+(2*3)+(1*9)=159
159 % 10 = 9
So 244757-39-9 is a valid CAS Registry Number.

Nucleophilic substitution reaction of 3-acetyl-1-methoxyindole and its application for the synthesis of novel 2-substituted methyl 2,3-dihydro-1- methyl-3-oxo-5H-pyrido-[4,3-b]indole-4-carboxylates

, p. 1949 - 1956 (1999)

A simple synthetic route was established for 3-acetyl-1-methoxyindole, which was found to undergo nucleophilic substitution reactions selectively at the 2-position. Applying the reaction, novel 2-substituted methyl 2,3- dihydro-1-methyl-3-oxo-5H-pyrido[4,3-b]indole-4-carboxylates were prepared.
