Check Digit Verification of cas no

The CAS Registry Mumber 1234338-22-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,4,3,3 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1234338-22:
(9*1)+(8*2)+(7*3)+(6*4)+(5*3)+(4*3)+(3*8)+(2*2)+(1*2)=127
127 % 10 = 7
So 1234338-22-7 is a valid CAS Registry Number.

Pd(OAc)2-catalyzed regioselective arylation of indoles with arylsiloxane in acidic medium

Liang, Zunjun,Yao, Bangben,Zhang, Yuhong

supporting information; scheme or table, p. 3185 - 3187 (2010/08/20)

(Figure Presented) Mild conditions have been developed to achieve a Pd(OAc)2-catalyzed cross-coupling between indoles and arylsiloxanes in the presence of TBAF and Ag2O in acidic medium. Electron-deficient arylsiloxanes presented high efficiency in this system to give the arylated indoles in excellent yields.
