Check Digit Verification of cas no

The CAS Registry Mumber 1235886-07-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,5,8,8 and 6 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1235886-07:
(9*1)+(8*2)+(7*3)+(6*5)+(5*8)+(4*8)+(3*6)+(2*0)+(1*7)=173
173 % 10 = 3
So 1235886-07-3 is a valid CAS Registry Number.

Palladium-catalyzed direct oxidative Heck-Cassar-Sonogashira type alkynylation of indoles with alkynes under oxygen

Yang, Luo,Zhao, Liang,Li, Chao-Jun

supporting information; experimental part, p. 4184 - 4186 (2010/08/19)

A novel PdII catalyzed direct oxidative Heck-Cassar-Sonogashira type alkynylation of indoles with terminal alkynes under an atmosphere of O 2 is developed. Unlike previous methods, the reaction does not require the pregeneration of indolyl halide or alkynyl halide. Furthermore, only a catalytic amount of base is required and oxygen was used as the ultimate green terminal oxidant.
