Check Digit Verification of cas no

The CAS Registry Mumber 21227-24-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,2 and 7 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 21227-24:
(7*2)+(6*1)+(5*2)+(4*2)+(3*7)+(2*2)+(1*4)=67
67 % 10 = 7
So 21227-24-7 is a valid CAS Registry Number.

Reduction of bis(triorganotin) oxides by metals: An easy route to hexaorganoditins

Jousseaume, Bernard,Chanson, Evelyne,Pereyre, Michel

, p. 1271 - 1272 (1986)

Bis(triorganotin) oxides have been reduced in high yield to hexaorganoditins by titanium, magnesium, potassium, and sodium.

A NEW PREPARATION OF HEXAALKYLDITINS. 119Sn NMR AND CHROMATOGRAPHIC DATA ON LINEAR POLYTINS

Jousseaume, Bernard,Chanson, Evelyne,Bevilacqua, Marcel,Saux, Annie,Pereyre, Michel,et al.

, p. C41 - C45 (2007/10/02)

The reaction of triorganotin oxides and formic acid provides a good route to ditin derivatives.Several new linear polytin compounds have been isolated, and the vicinal and long range 119Sn-119Sn coupling constants determined.A linear relationship has been demonstrated between the logarithm of the HPLC retention time and the number of tin atoms in the compounds.
