Check Digit Verification of cas no

The CAS Registry Mumber 23138-98-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,1,3 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 23138-98:
(7*2)+(6*3)+(5*1)+(4*3)+(3*8)+(2*9)+(1*8)=99
99 % 10 = 9
So 23138-98-9 is a valid CAS Registry Number.

Splitting a Substrate into Three Parts: Gold-Catalyzed Nitrogenation of Alkynes by C-C and C≡C Bond Cleavage

Qin, Chong,Su, Yijin,Shen, Tao,Shi, Xiaodong,Jiao, Ning

, p. 350 - 354 (2016)

A gold-catalyzed nitrogenation of alkynes for the synthesis of carbamides and amino tetrazoles through C-C and C≡C bond cleavages is described. A diverse set of functionalized carbamide and amino tetrazole derivatives were selectively constructed under mild conditions. The chemoselectivity can be easily switched by the selection of the acid additives. The reaction is characterized by its broad substrate scope, direct construction of high value products, easy operation under air, and mild conditions at room temperature. This chemistry provides a way to transform alkynes by splitting the substrate into three parts.
