Check Digit Verification of cas no

The CAS Registry Mumber 6577-97-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,7 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6577-97:
(6*6)+(5*5)+(4*7)+(3*7)+(2*9)+(1*7)=135
135 % 10 = 5
So 6577-97-5 is a valid CAS Registry Number.

, p. 8533 - 8538 (2007/10/03)

Facile and one-pot synthetic route of poly-substituted pyrroles and 4-oxo-4,5,6,7-tetrahydroindoles is established, which consists of three steps: (1) palladium-catalyzed oxidation of hydroxy-enamines by using tetrakis(triphenylphosphine)palladium and mesityl bromide oxidation system, (2) intramolecular cyclization, and (3) dehydration.
