Check Digit Verification of cas no

The CAS Registry Mumber 1428367-94-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,3,6 and 7 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1428367-94:
(9*1)+(8*4)+(7*2)+(6*8)+(5*3)+(4*6)+(3*7)+(2*9)+(1*4)=185
185 % 10 = 5
So 1428367-94-5 is a valid CAS Registry Number.

Rhodium(III)-catalyzed direct selective C(5)-H oxidative annulations of 2-substituted imidazoles and alkynes by double C-H activation

Huang, Ji-Rong,Zhang, Qian-Ru,Qu, Chuan-Hua,Sun, Xun-Hao,Dong, Lin,Chen, Ying-Chun

supporting information, p. 1878 - 1881 (2013/05/23)

Double C-H activations of C(5)-H and Csp2-H of 2-substituted N-vinyl- or arylimidazoles were realized without heteroatom-directing assistance by rhodium(III) catalyst. A subsequent oxidative annulation reaction with alkynes efficiently produced aza-fused heterocycles with high molecular complexity in low to excellent yields.
