Check Digit Verification of cas no
The CAS Registry Mumber 71149-34-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,1,4 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 71149-34:
(7*7)+(6*1)+(5*1)+(4*4)+(3*9)+(2*3)+(1*4)=113
113 % 10 = 3
So 71149-34-3 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.
