Check Digit Verification of cas no

The CAS Registry Mumber 132902-39-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,9,0 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 132902-39:
(8*1)+(7*3)+(6*2)+(5*9)+(4*0)+(3*2)+(2*3)+(1*9)=107
107 % 10 = 7
So 132902-39-7 is a valid CAS Registry Number.

Asymmetric Catalysis, Part 91: Enantioselective Monophenylation of cis-1,2-Cyclopentanediol with Triphenylbismuth Diacetate and Chiral Copper(II) Complexes as Catalysts

Brunner, H.,Chuard, T.

, p. 1293 - 1300 (2007/10/02)

The monophenylation of cis-1,2-cyclopentanediol with triphenylbismuth diacetate in the presence of chiral Cu(II) complexes as catalysts gave cis-2-hydroxy-1-phenoxy-cyclopentane with enantiomeric excesses up to 38percent.The optically active ligands used were triamine derivatives of 2,6-bis(aminomethyl)pyridine and diamine derivatives of 2-(aminomethyl)pyridine.Selectivity in the monophenylation occurred only in the presence of the latter as auxiliary ligands. - Keywords.Enantioselective catalysis; Chiral Cu(II) complexes; Monophenylation; Triphenylbismuth diacetate; cis-1,2-Cyclopentanediol.
