Check Digit Verification of cas no

The CAS Registry Mumber 180737-44-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,7,3 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 180737-44:
(8*1)+(7*8)+(6*0)+(5*7)+(4*3)+(3*7)+(2*4)+(1*4)=144
144 % 10 = 4
So 180737-44-4 is a valid CAS Registry Number.

Bis(stannyl)phosphanyl-substituted dichlorosilanes/germanes - Potential precursors for a novel strategy toward P-Si/Ge multiple bonds?

Bender, Marion,Niecke, Edgar,Nieger, Martin,Pietschnig, Rudolf

, p. 380 - 384 (2006)

A general synthetic route to bis(stannyl)phosphanyl-substituted dichlorosilanes/germanes of the type R-SiCl2-P(SnMe3) 2 and R-GeCl2-P(SnMe3)2 is reported. For R = Cp* (= 1,2,3,4,5-pentamethylcyclopentadienyl) crystal structures for the corresponding silane and germane could be obtained. These compounds are the first structurally characterized bis-(stannyl)phosphanyl-substituted dichlorosilanes/germanes that due to their functionalities should be ideal precursors for the generation of unsaturated PSi and PGe units and possibly phosphasilynes and phosphagermynes.
