Check Digit Verification of cas no

The CAS Registry Mumber 13904-38-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,9,0 and 4 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 13904-38:
(7*1)+(6*3)+(5*9)+(4*0)+(3*4)+(2*3)+(1*8)=96
96 % 10 = 6
So 13904-38-6 is a valid CAS Registry Number.

Microwave-assisted Lewis acid catalysis: Application to the synthesis of alkyl- or arylhalogermanes

Laurent, Régis,Laporterie, André,Dubac, Jacques,Berlan, Jacques

, p. 2493 - 2495 (2008/10/08)

Under microwave irradiation, alkyl- or arylhalogermanes RnGeX4-n (R = Et, Bu, Ph; X = Cl, Br) are obtained by redistribution reactions of R4Ge with GeX4. These experimental conditions permit the synthesis of such compounds in good yield in a few minutes at atmospheric pressure. The direct Friedel-Crafts germylation of benzene and toluene by germanium tetrachloride also has been performed, but yields were low.
