Check Digit Verification of cas no

The CAS Registry Mumber 676465-37-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,6,4,6 and 5 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 676465-37:
(8*6)+(7*7)+(6*6)+(5*4)+(4*6)+(3*5)+(2*3)+(1*7)=205
205 % 10 = 5
So 676465-37-5 is a valid CAS Registry Number.

A Concise Route to 2-Amino-3-aryl-3H-benzofurans and their Use as Precursors to 3-Aryl-3H-benzofuran-2-one and 1H-Benzofuro[2,3-￡]pyridin-2- one Derivatives

Gerster, Michele,Wicki, Reto

, p. 249 - 254 (2007/10/03)

A concise approach to 2-amino-3-aryl-3H-benzofurans based on the Michael addition of NaCN onto in situ generated substituted o-quinone methides has been developed. Straightforward access to 3-aryl-3H-benzofuran-2-ones was achieved upon acidic hydrolysis whereas JV-Boc-protected 2-amino-3-aryl-3H-benzofurans underwent smooth intramolecular cyclisation to give 1H-benzofuro[2,3-b]pyridin- 2-one derivatives.
