Check Digit Verification of cas no

The CAS Registry Mumber 195388-47-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,5,3,8 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 195388-47:
(8*1)+(7*9)+(6*5)+(5*3)+(4*8)+(3*8)+(2*4)+(1*7)=187
187 % 10 = 7
So 195388-47-7 is a valid CAS Registry Number.

Asymmetric Hydroxylation, Epoxidation and Sulfoxidation Catalyzed by Vaulted Binaphthyl Metalloporphyrins

Groves, John T.,Viski, Peter

, p. 3628 - 3634 (1990)

A chiral, vaulted binaphthyl porphyrin (1) has been prepared from 5α,10β,15α,20β-tetrakis(o-aminophenyl)porphyrin and (R)-(+)-2,2'-dimethoxy-1,1'-bi-6-naphthoyl chloride in 79 percent yield.Asymmetric oxygenations of alkanes, alkenes, and alkyl sulfides were catalyzed with the chloroiron(III) and chloromanganese(III) complexes of 1 with good yields and high stereoselectivities.The first catalytic asymmetric hydroxylations are reported for 1-Fe(III)Cl with enantiomeric excesses in the range of 40-72 percent.The corresponding manganese catalyst, 1-Mn(III)Cl, gave much lower enantiomeric excesses.For catalytic asymmetric epoxidations, enantiomeric excesses were in the range of 20-72 percent.Prochiral alkyl sulfides gave sulfoxides with 14-48 percent ee with 1-Fe(III)Cl.
