Check Digit Verification of cas no
The CAS Registry Mumber 514806-81-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,4,8,0 and 6 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 514806-81:
(8*5)+(7*1)+(6*4)+(5*8)+(4*0)+(3*6)+(2*8)+(1*1)=146
146 % 10 = 6
So 514806-81-6 is a valid CAS Registry Number.

Study of the addition of Grignard reagents to 2-aryl-3H-indol-3-ones
Liu, Yahua,McWhorter Jr., William W.
, p. 2618 - 2622 (2007/10/03)
Grignard reagents are added to the carbonyl group of 2-aryl-3H-indol-3-ones to generate 3-alkyl-(or phenyl)-2-aryl-3H-indol-3-ols, which are in turn rearranged to yield 2-alkyl(or phenyl)-2-aryl-1,2-dihydro-3H-indol-3-ones.
