Check Digit Verification of cas no

The CAS Registry Mumber 144646-90-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,6,4 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 144646-90:
(8*1)+(7*4)+(6*4)+(5*6)+(4*4)+(3*6)+(2*9)+(1*0)=142
142 % 10 = 2
So 144646-90-2 is a valid CAS Registry Number.

Palladium-catalyzed coupling of 3-indolyl triflate. Syntheses of 3-vinyl and 3-alkynylindoles

Gribble,Conway

, p. 2129 - 2141 (2007/10/02)

Palladium-catalyzed coupling of 1-(phenylsulfonyl)indol-3-yl trifluoromethanesulfonate (triflate) (1) with terminal alkenes and alkynes gives 3-vinyl (2) and 3-alkynylindoles in 45-93% yields. An attempt to generate 2,3-indolyne 22 from 2-trimethylsilyl-3-indolyl triflate 20 gives indigo (23).
