Check Digit Verification of cas no

The CAS Registry Mumber 203740-75-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,7,4 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 203740-75:
(8*2)+(7*0)+(6*3)+(5*7)+(4*4)+(3*0)+(2*7)+(1*5)=104
104 % 10 = 4
So 203740-75-4 is a valid CAS Registry Number.

Hydrostannylation of phosphaalkynes

Schmitz, Marion,Goeller, Rudolf,Bergstraesser, Uwe,Leininger, Stefan,Regitz, Manfred

, p. 227 - 235 (2007/10/03)

The hydrostannylation of phosphaalkynes 8 with tin hydrides 1 depends on the stoichiometry employed: Thus, the 1,2-dihydro-1,3-diphosphetes 10 are isolated when an excess of phosphaalkyne 8 is used. On the other hand, an increase in the tin hydride concentration favors the formation of the phosphanes 11 and 12. Synthesis of the 1,2-dihydro-1,3-diphosphetes 14 and 16 was achieved by the use of diorganotin hydrides 13 or chloro(organo)tin hydrides 4, respectively. An isolated and characterized by-product of the latter reaction was the phosphorus-carbon-tin cage 17. Furthermore, the following reactions of the 1,2-dihydro-1,3-diphosphetes 10 were performed: isomerization reactions, complexation reactions with transition-metal complexes, and substitution of the hydrogen atom by iodine.
