Check Digit Verification of cas no

The CAS Registry Mumber 20544-84-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,5,4 and 4 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 20544-84:
(7*2)+(6*0)+(5*5)+(4*4)+(3*4)+(2*8)+(1*4)=87
87 % 10 = 7
So 20544-84-7 is a valid CAS Registry Number.

Rh(ii)-catalyzed cycloadditions of 1-tosyl 1,2,3-triazoles with 2H-azirines: Switchable reactivity of Rh-azavinylcarbene as [2C]- or aza-[3C]-synthon

Wang, Yuanhao,Lei, Xiaoqiang,Tang, Yefeng

supporting information, p. 4507 - 4510 (2015/03/18)

The Rh(ii)-catalyzed formal [3+2] and [3+3] cycloadditions of 1-tosyl 1,2,3-triazoles with 2H-azirines have been developed, which enable the efficient synthesis of polysubstituted 3-aminopyrroles and 1,2-dihydropyrazines, respectively. The reported [3+2] cycloaddition represents the first application of 1-sulfonyl 1,2,3-triazole as a [2C]-component in relevant cycloaddition reactions. This journal is
