3189-12-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3189-12-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,8 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3189-12:
(6*3)+(5*1)+(4*8)+(3*9)+(2*1)+(1*2)=86
86 % 10 = 6
So 3189-12-6 is a valid CAS Registry Number.

One-pot N-alkylation/Heck approach to substituted indoles
Weinrich, Melissa L.,Beck, Hilary P.
scheme or table, 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.
