Check Digit Verification of cas no

The CAS Registry Mumber 30343-28-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,3,4 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 30343-28:
(7*3)+(6*0)+(5*3)+(4*4)+(3*3)+(2*2)+(1*8)=73
73 % 10 = 3
So 30343-28-3 is a valid CAS Registry Number.

Pd-catalyzed intramolecular Heck reaction for the synthesis of 2-methylbenzofurans

Zhou,Shi, Yuxing,Zhu, Xueyan,Zhang, Peng

supporting information, p. 2005 - 2008 (2019/07/03)

A new strategy for the synthesis of 2-Methylbenzofurans via the intramolecular Heck reaction has been developed. This efficient palladium-catalyzed system showed good catalytic activity. Various substituted 2-methylbenzofurans could be afforded in good to excellent yields.
