Check Digit Verification of cas no

The CAS Registry Mumber 792903-34-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,9,2,9,0 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 792903-34:
(8*7)+(7*9)+(6*2)+(5*9)+(4*0)+(3*3)+(2*3)+(1*4)=195
195 % 10 = 5
So 792903-34-5 is a valid CAS Registry Number.

Intramolecular Mannich reaction of 2-oxotryptamine and homologues with oxo reagents yielding spiro compounds. Part II

Doernyei, Gabor,Incze, Maria,Kajtar-Peredy, Maria,Szantay, Csaba

, p. 1669 - 1680 (2002)

2-Oxotryptamine and its homo derivative undergo intramolecular Mannich-type cyclization with acetone and other ketones to give spiro[indole-3,3′-pyrrolidin]-2-ones and spiro[indole-3,3′-piperidin]-2-ones. A similar reaction with the bis-homologue of 2-oxotryptamine to yield spiro[azepane-3,3′-indol]-2′-ones was unsuccessful.
