1575721-39-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1575721-39-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,7,5,7,2 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1575721-39:
(9*1)+(8*5)+(7*7)+(6*5)+(5*7)+(4*2)+(3*1)+(2*3)+(1*9)=189
189 % 10 = 9
So 1575721-39-9 is a valid CAS Registry Number.

Palladium-catalysed ligand-free reductive Heck cycloisomerisation of 1,6-en-α-chloro-enamides
Hou, Yangyang,Ma, Jing,Yang, Hongyi,Anderson, Edward A.,Whiting, Andy,Wu, Na
, p. 3733 - 3736 (2019/04/01)
The first example of an intramolecular hydroarylation of 1,6-en-α-chloro-enamides was achieved by a palladium-catalysed ligand-free reductive Heck cycloisomerisation with no competing Heck-cyclised by-product.
