Check Digit Verification of cas no

The CAS Registry Mumber 1428872-73-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,8,7 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1428872-73:
(9*1)+(8*4)+(7*2)+(6*8)+(5*8)+(4*7)+(3*2)+(2*7)+(1*3)=194
194 % 10 = 4
So 1428872-73-4 is a valid CAS Registry Number.

Pd/C-catalyzed cyclizative cross-coupling of two ortho-alkynylanilines under aerobic conditions: Synthesis of 2,3′-bisindoles

Yao, Bo,Wang, Qian,Zhu, Jieping

, p. 7413 - 7416 (2015)

Abstract A palladium-catalyzed cyclizative cross-coupling of two o-alkynylanilines to 2,3′-bisindoles under aerobic oxidative conditions was developed. Mechanistic studies suggested that the two catalytic cycles, namely the formation of 3-alkynylindoles 8
