Check Digit Verification of cas no
The CAS Registry Mumber 74420-08-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,2 and 0 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 74420-08:
(7*7)+(6*4)+(5*4)+(4*2)+(3*0)+(2*0)+(1*8)=109
109 % 10 = 9
So 74420-08-9 is a valid CAS Registry Number.

Synthesis of 4-Amino-1H-pyrrolopyridine (1,7-Dideazaadenine) and 1H-Pyrrolopyridin-4-ol (1,7-Dideazahypoxanthine)

4-Amino-1H-pyrrolopyridine (1,7-dideazaadenine) (5) has been synthesized by the iron and acetic acid reduction of 4-nitro-1H-pyrrolopyridine 7-oxide (13), obtained by nitration of 1H-pyrrolopyridine-3-carboxamide 7-oxide (17).Other nitration reactions in the 1H-pyrrolopyridine 7-oxide series are disclosed.The preparation of 1H-pyrrolopyridin-4-ol (1,7-dideazahypoxanthine) (6) began with the hydrolysis of ethyl 1-benzyl-3-cyano-4-oxo-4,7-dihydro-1H-pyrrolopyridine-5-carboxylate (21) to the 3,5-dicarboxylic acid derivative of 1-benzyl-4-oxo-4,7-dihydro-1H-pyrrolopyridine (22).Decarboxylation of 22 with subsequent debenzylation formed 6.
