946403-38-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 946403-38-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,6,4,0 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 946403-38:
(8*9)+(7*4)+(6*6)+(5*4)+(4*0)+(3*3)+(2*3)+(1*8)=179
179 % 10 = 9
So 946403-38-9 is a valid CAS Registry Number.

Synthesis of 3-amino-5H-pyrrolo[2,3-e]-1,2,4-triazines by Sonogashira/copper(I)-catalyzed heteroannulation
Nyffenegger, Coralie,Fournet, Guy,Joseph, Beno?t
, p. 5069 - 5072 (2007)
A Sonogashira/copper(I)-catalyzed heteroannulation sequence was developed to convert 3,5-diamino-6-chloro-1,2,4-triazines to the corresponding 3-amino-5H-pyrrolo[2,3-e]-1,2,4-triazine derivatives in good yields.
