Check Digit Verification of cas no

The CAS Registry Mumber 1374875-73-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,4,8,7 and 5 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1374875-73:
(9*1)+(8*3)+(7*7)+(6*4)+(5*8)+(4*7)+(3*5)+(2*7)+(1*3)=206
206 % 10 = 6
So 1374875-73-6 is a valid CAS Registry Number.

Double N-arylation reaction of polyhalogenated 4,4'-bipyridines. Expedious synthesis of functionalized 2,7-diazacarbazoles

Abboud, Mohamed,Aubert, Emmanuel,Mamane, Victor

supporting information; experimental part, p. 253 - 258 (2012/05/05)

Unusual 2,7-diazacarbazoles were prepared in one step from readily available tetra-halogenated 4,4'-bipyridines by using a double N-arylation reaction in the presence of the Pd-XPhos catalyst system. Moderate to good yields were obtained in this site-sele
