Check Digit Verification of cas no

The CAS Registry Mumber 1402134-31-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,2,1,3 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1402134-31:
(9*1)+(8*4)+(7*0)+(6*2)+(5*1)+(4*3)+(3*4)+(2*3)+(1*1)=89
89 % 10 = 9
So 1402134-31-9 is a valid CAS Registry Number.

Interfacial synthesis of crystalline two-dimensional cyano-graphdiyne

Chen, Siqi,Li, Zhibo,Pan, Qingyan,Shao, Feng,Sun, Qingzhu,Wu, Chenyu,Zhang, Zhaohui,Zhao, Yingjie

, p. 3210 - 3213 (2020)

A well-defined crystalline cyano-functionalized graphdiyne (CN-GDY) is synthesized at a liquid/liquid interface through alkyne-alkyne coupling reactions. The configurations and nanostructures of CN-GDY were well characterized by TEM, SEM, AFM, XPS, and Raman spectroscopy. HR-TEM and selected area electron diffraction (SAED) in combination with structure simulation firmly revealed a 9-fold stacking mode for CN-GDY.
