Check Digit Verification of cas no

The CAS Registry Mumber 309956-03-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,9,9,5 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 309956-03:
(8*3)+(7*0)+(6*9)+(5*9)+(4*5)+(3*6)+(2*0)+(1*3)=164
164 % 10 = 4
So 309956-03-4 is a valid CAS Registry Number.

Six-coordinate aluminium phosphinate

Wang,Parkin,Atwood

, p. 1799 - 1800 (2000)

Unique models of solid state aluminophosphate materials containing, for the first time, six-coordinate aluminium atoms, may be achieved in chelated phosphinate derivatives; the degree of aggregation of these species, specifically the remarkable transition from a dimeric molecule to a polymeric material, depends on just one methylene unit; thus, [(Bu(t)4salpen)Al{O2P(H)Ph}]2 1 is dimeric while [(Bu(t)4salen)Al{O2P(H)Ph}](∞) 2, with one fewer methylene unit in the connection between the two nitrogens, is a polymeric material with the polymers aligned to form pores containing thf molecules.
