Check Digit Verification of cas no

The CAS Registry Mumber 1421276-40-5 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, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1421276-40:
(9*1)+(8*4)+(7*2)+(6*1)+(5*2)+(4*7)+(3*6)+(2*4)+(1*0)=125
125 % 10 = 5
So 1421276-40-5 is a valid CAS Registry Number.

Direct access to acylated azobenzenes via Pd-catalyzed C-H functionalization and further transformation into an indazole backbone

Li, Hongji,Li, Pinhua,Wang, Lei

, p. 620 - 623 (2013/04/10)

Azobenzenes were readily acylated at the 2-position through a Pd-catalyzed C-H functionalization from simple aromatic azo compounds and aldehydes in good yields. The obtained acylated azobenzenes could be efficiently converted into the corresponding indaz
