117012-57-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117012-57-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,0,1 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 117012-57:
(8*1)+(7*1)+(6*7)+(5*0)+(4*1)+(3*2)+(2*5)+(1*7)=84
84 % 10 = 4
So 117012-57-4 is a valid CAS Registry Number.

Mixed triorganotin compounds, R3Sn-X-SnR'3: 119Sn NMR evidence for their formation in solution
Blunden, S. J.,Hill, R.
, p. 317 - 322 (2007/10/02)
119Sn NMR spectroscopy has been used to demonstrate the existence, for hte first time, of mixed triorganotin compounds, R3Sn-X-SnR'3, where R or R' = Bu, Ph or cyclo-C6H11 and X = O or S.These species exist in solution in equilibrium with the correspondin
