Check Digit Verification of cas no

The CAS Registry Mumber 1426306-74-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,6,3,0 and 6 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1426306-74:
(9*1)+(8*4)+(7*2)+(6*6)+(5*3)+(4*0)+(3*6)+(2*7)+(1*4)=142
142 % 10 = 2
So 1426306-74-2 is a valid CAS Registry Number.

N-heterocyclic carbene-palladium(II)-1-methylimidazole complex catalyzed α-arylation of oxindoles with aryl chlorides and aerobic oxidation of the products in a one-pot procedure

Xiao, Zheng-Kang,Yin, Hui-Ying,Shao, Li-Xiong

supporting information, p. 1254 - 1257 (2013/04/23)

NHC-Pd(II)-Im complex 1 was found to be an effective catalyst for the α-arylation of unprotected oxindoles with aryl chlorides to give products 4 in 44-98% yields under a N2 atmosphere. Furthermore, if the reactions were first performed under conditions identical to those for the α-arylation reaction for 12 h and then exposed to air for another 3 h, 3-aryl-3-hydroxy-2-oxindoles 5 can be obtained in 49-84% yields in a one-pot procedure.
