1435459-47-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1435459-47-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,5,4,5 and 9 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1435459-47:
(9*1)+(8*4)+(7*3)+(6*5)+(5*4)+(4*5)+(3*9)+(2*4)+(1*7)=174
174 % 10 = 4
So 1435459-47-4 is a valid CAS Registry Number.

Synthesis of thiophene-based TAK-779 analogues by C-H arylation
Junker, Anna,Yamaguchi, Junichiro,Itami, Kenichiro,Wünsch, Bernhard
, p. 5579 - 5586 (2013/07/26)
A rapid synthesis of thiophene-based TAK-779 analogues 1 is reported using a late-stage diversification strategy. At the end of the synthesis, the key building block 2, which was prepared in six steps from thiophene, was arylated regioselectively at the α
