13519-87-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 13519-87-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,5,1 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 13519-87:
(7*1)+(6*3)+(5*5)+(4*1)+(3*9)+(2*8)+(1*7)=104
104 % 10 = 4
So 13519-87-4 is a valid CAS Registry Number.

One-pot N-alkylation/Heck approach to substituted indoles
Weinrich, Melissa L.,Beck, Hilary P.
experimental part, p. 6968 - 6972 (2010/02/27)
Here, we report the palladium-catalyzed one-pot N-alkylation/Heck cyclization of anilines to substituted indoles employing Pd(OAc)2/XPhos. The scope and limitations of this methodology will be described.
