Check Digit Verification of cas no

The CAS Registry Mumber 104284-14-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,2,8 and 4 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 104284-14:
(8*1)+(7*0)+(6*4)+(5*2)+(4*8)+(3*4)+(2*1)+(1*4)=92
92 % 10 = 2
So 104284-14-2 is a valid CAS Registry Number.

Quelques aspects de la chimie des dioxa- et dithia-germoles

Lavayssiere, H.,Satge, G. Dousse et J.

, p. 440 - 448 (2007/10/02)

Dithia- and dioxa-germoles: (X=S, O), have been prepared from diorganodihalogermanes and R'(NaS)C=C(SNa)R', 1,2-benzenedithiol, α-hydroxy ketones, R''(KO)C=C(OK)R'' or dioxastannole and by cleavage of Ge-N bonds of diorganobis(diethylamino)germanes by benzoin.The synthesis of spirobidithiagermoles is also reported.The thermal stability of dithiagermoles has been studied.Decomposition occurs mostly by a ring opening with formation of germathiones.In the presence of tertiary amines, dioxagermoles lead to germylenes and α-diketones through a ring opening.The chemical reactivity of dithia- and dioxa-germoles has been studied.Exchange reactions with dihalogenated covalent compounds occur readily leading to carbon, phosphorus and sulfur dithiole and dioxole analogs.From dichlorogermylene new stable functional cyclic germylenes are obtained and characterized.
