1384290-43-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1384290-43-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,4,2,9 and 0 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1384290-43:
(9*1)+(8*3)+(7*8)+(6*4)+(5*2)+(4*9)+(3*0)+(2*4)+(1*3)=170
170 % 10 = 0
So 1384290-43-0 is a valid CAS Registry Number.

Intramolecular hydrogen bonding-assisted cyclocondensation of α-diazoketones with various amines: A strategy for highly efficient Wolff 1,2,3-triazole synthesis

Wang, Zikun,Bi, Xihe,Liao, Peiqiu,Zhang, Rui,Liang, Yongjiu,Dong, Dewen

supporting information; experimental part, p. 7076 - 7078 (2012/08/14)

A catalytic and highly efficient Wolff's cyclocondensation of α-diazoketones with aromatic and aliphatic amines has been realized for the first time by utilizing the strategy of an intramolecular hydrogen bonding-activating carbonyl group. This approach successfully solved the challenging problem of poor condensation efficiency in Wolff 1,2,3-triazole synthesis, and constitutes a powerful method for the synthesis of highly functionalized 1,2,3-triazoles.
