Check Digit Verification of cas no

The CAS Registry Mumber 226895-33-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,6,8,9 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 226895-33:
(8*2)+(7*2)+(6*6)+(5*8)+(4*9)+(3*5)+(2*3)+(1*3)=166
166 % 10 = 6
So 226895-33-6 is a valid CAS Registry Number.

Palladium-catalyzed synthesis of fused indoles

Soederberg, Bjoern C.,Rector, Stacey R.,O'Neil, Shannon N.

, p. 3657 - 3660 (1999)

A novel route to fused indoles via two consecutive palladium catalyzed reactions, an intramolecular Heck reaction followed by a reductive N- heteroannulation, has been developed. For example, reaction of 2-bromo-3- nitro-1(3-butenyloxy)benzene with pallad
