26128-31-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 26128-31-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,1,2 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 26128-31:
(7*2)+(6*6)+(5*1)+(4*2)+(3*8)+(2*3)+(1*1)=94
94 % 10 = 4
So 26128-31-4 is a valid CAS Registry Number.

Regioselective oxidation of steroids by a manganese porphyrin carrying metal coordinating groups
Belvedere, Sandro,Breslow, Ronald
, p. 321 - 331 (2007/10/03)
A manganese porphyrin having tour 2,2′-bipyridyl groups on its meso positions was synthesized. In the presence of Cu2+ ions it catalyzes the regioselective oxidation of steroid substrates carrying auxiliary metal coordinating groups.
