Check Digit Verification of cas no

The CAS Registry Mumber 1374963-75-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,4,9,6 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1374963-75:
(9*1)+(8*3)+(7*7)+(6*4)+(5*9)+(4*6)+(3*3)+(2*7)+(1*5)=203
203 % 10 = 3
So 1374963-75-3 is a valid CAS Registry Number.

N-transfer reagent and method for preparing the same and its application

-

Page/Page column 22-23; 47-50; 51-54, (2021/06/25)

Provided are a novel N-transfer reagent and a method for preparing the same and its application. The N-transfer reagent is represented by the following Formula (I): The various novel N-transfer reagents of the present invention can be quickly prepared by employing different nitrobenzene precursors. The N-transfer reagents can directly convert a variety of amino compounds into diazo compounds under mild conditions. Particularly, the N-transfer reagents can facilitate the synthesis of the diazo compounds. The application of synthesizing diazo compounds of the present invention can greatly decrease the difficulty in operation, increase the safety during experiments, reduce the cost of production and the environmental pollution, and enhance the industrial value of diazo compounds.
