129271-97-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129271-97-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,2,7 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 129271-97:
(8*1)+(7*2)+(6*9)+(5*2)+(4*7)+(3*1)+(2*9)+(1*7)=142
142 % 10 = 2
So 129271-97-2 is a valid CAS Registry Number.

SYNTHESIS OF 1-(PHENYLSULFONYL)INDOL-3-YL TRIFLUOROMETHANESULFONATE
Conway, Samuel C.,Gribble, Gordon W.
, p. 627 - 633 (2007/10/02)
The synthesis of the potentially useful intermediate 1-(phenylsulfonyl)indol-3-yl trifluoromethanesulfonate (triflate) (1), via several approaches to the corresponding indoxyl 6, is decsribed.Of these, the direct oxidation of 1-(phenylsulfonyl)indole (2)
