Check Digit Verification of cas no

The CAS Registry Mumber 1438416-86-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,8,4,1 and 6 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1438416-86:
(9*1)+(8*4)+(7*3)+(6*8)+(5*4)+(4*1)+(3*6)+(2*8)+(1*6)=174
174 % 10 = 4
So 1438416-86-4 is a valid CAS Registry Number.

Efficient synthesis of 2-arylamino substituted pyridinyl nitriles by Buchwald-Hartwig amination

Guo, Shuo,Wang, Yaping,Sun, Chunxia,Li, Jingya,Zou, Dapeng,Wu, Yangjie,Wu, Yusheng

supporting information, p. 3233 - 3237 (2013/06/27)

Both nitrile and arylamino groups containing pyridine derivatives are synthesized from commercially available nitrile substituted pyridyl chlorides via a palladium-BINAP catalyst (the second generation catalyst for the amination) in moderate to good yields. The mild conditions permit the presence of base sensitive functional groups. Noteably, the halogen atoms linked to the aromatic ring were maintained in the structures of the products under the amination reaction conditions.
