Check Digit Verification of cas no

The CAS Registry Mumber 134152-73-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,1,5 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 134152-73:
(8*1)+(7*3)+(6*4)+(5*1)+(4*5)+(3*2)+(2*7)+(1*3)=101
101 % 10 = 1
So 134152-73-1 is a valid CAS Registry Number.

Metal-Containing Heterocycles: Preparation, Properties, Reactions, LXXV. - Synthesis of a Diphosphamolybdacyclopentene by Alkyne Insertion into the P-P Bond of a Diphosphamolybdacyclopropane

Lindner, Ekkehard,Heckmann, Maria

, p. 1715 - 1716 (2007/10/02)

Insertion of the alkyne RCCR (R= CO2Me) into the P-P bond of the diphosphamolybdacyclopropane (η5-C5H5)-(OC)2Mo-PPh2-PAr (2) results in the formation of the thermally and kinetically stable diphosphamolybdacyclopentene (η5-C5H5)(OC)2Mo-PPh2-RC=CR-PAr (3), which is characterized on the basis of mass, IR, 31P-, 1H-, and 13C-NMR spectra. Key Words: P-P bond/ Alkyne insertion/ Diphosphamolybdacyclopentene
