Check Digit Verification of cas no

The CAS Registry Mumber 104677-50-1 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 0 respectively.
Calculate Digit Verification of CAS Registry Number 104677-50:
(8*1)+(7*0)+(6*4)+(5*6)+(4*7)+(3*7)+(2*5)+(1*0)=121
121 % 10 = 1
So 104677-50-1 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 (1986)

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.
