104677-52-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104677-52-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,6,7 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 104677-52:
(8*1)+(7*0)+(6*4)+(5*6)+(4*7)+(3*7)+(2*5)+(1*2)=123
123 % 10 = 3
So 104677-52-3 is a valid CAS Registry Number.

Catalysed Epoxidation and Hydroxylation of Alkene by Osmium(III)-Porphyrin Complexes
Che, Chi-Ming,Chung, Wai-Cheung
, p. 386 - 388 (2007/10/02)
Osmium(III)-porphyrin complexes have been prepared by Br2 oxidation of Os(II)(P)(P-n-Bu3)(CO) in CH2Cl2 ; the 'Os(III)(P)(P-n-Bu3)Br = PhIO' system is capable of performing epoxidation and hydroxylation of styrene and cyclohexene.
