Check Digit Verification of cas no

The CAS Registry Mumber 1421276-28-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,2,7 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1421276-28:
(9*1)+(8*4)+(7*2)+(6*1)+(5*2)+(4*7)+(3*6)+(2*2)+(1*8)=129
129 % 10 = 9
So 1421276-28-9 is a valid CAS Registry Number.

A highly efficient palladium-catalyzed decarboxylative ortho-acylation of azobenzenes with α-oxocarboxylic acids: Direct access to acylated azo compounds

Li, Hongji,Li, Pinhua,Tan, Hui,Wang, Lei

supporting information, p. 14432 - 14436 (2013/11/06)

Avoiding additives: A highly efficient and mild Pd-catalyzed decarboxylative ortho-acylation of azobenzenes with α-oxocarboxylic acids was developed that provides an alternative route to acylated azo compounds. This decarboxylative acylation process was completed in the absence of any additives at ambient temperature, to afford the acylated azobenzenes in moderate to good yields (see scheme). Copyright
