Check Digit Verification of cas no

The CAS Registry Mumber 170307-14-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,3,0 and 7 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 170307-14:
(8*1)+(7*7)+(6*0)+(5*3)+(4*0)+(3*7)+(2*1)+(1*4)=99
99 % 10 = 9
So 170307-14-9 is a valid CAS Registry Number.

ETUDE DE NOUVELLES REACTIONS PAR TRANSFERT MONOELECTRONIQUE: ACTION D'ORGANOGERMYLLITHIUMS SUR LE FURFURAL, LE THIOPHENALDEHYDE ET LES DERIVES NITRES CORRESPONDANTS

Riviere, P.,Castel, A.,Cosledan, F.

, p. 169 - 180 (2007/10/02)

The organogermyllithiums R3GeLi (R=Ph, Mes) were treated with several carbonyl conjugated substrates (2-furaldehyde, 2-thiophenecarboxaldehyde and their nitro-corresponding compounds).Only the germylation reactions of carbonyl group have been observed with a regioselectivity depending on the nature of the insaturated cycle.With 2-furaldehyde and 2-thiophenecarboxaldehyde, the germylcarbinols 1 are mainly obtained by C-germylation reaction.When an excess of aldehyde was used, the formation of germylketone 2 is surprisingly observed.With nitro compounds, the O-germylation reaction is preponderant.In this case, a single electron transfer mechanism takes place and was confirmed by ESR study.We observed the corresponding organic radical anion.The hyperfine structure of which has been resolved.Key words: SET reactions, germylation, radical anion, germyllithiums, germylketones, germanium centered radical.
