400628-57-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 400628-57-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,0,6,2 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 400628-57:
(8*4)+(7*0)+(6*0)+(5*6)+(4*2)+(3*8)+(2*5)+(1*7)=111
111 % 10 = 1
So 400628-57-1 is a valid CAS Registry Number.

Manganese as a template: A new synthesis of corrole
Broering,Hell
, p. 2336 - 2337 (2007/10/03)
The reaction of 2,2′-bisdipyrrins 1, 2, and 3 with manganese(II) acetate tetrahydrate and molecular dioxygen yields the manganese(III)corroles 4, 5 and 6, which are readily demetalated to the respective free-base corroles.
