19859-12-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 19859-12-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,8,5 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 19859-12:
(7*1)+(6*9)+(5*8)+(4*5)+(3*9)+(2*1)+(1*2)=152
152 % 10 = 2
So 19859-12-2 is a valid CAS Registry Number.

Intramolecular C-H amination with sulfonyl azides
-
Page/Page column 9-10, (2010/04/23)
Cobalt (II) complexes of porphyrins are effective catalysts for intramolecular nitrene insertion of C—H bonds with arylsulfonyl azides. The cobalt-catalyzed process can proceed efficiently under mild and neutral conditions in low catalyst loading without
