62690-40-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 62690-40-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,6,9 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 62690-40:
(7*6)+(6*2)+(5*6)+(4*9)+(3*0)+(2*4)+(1*0)=128
128 % 10 = 8
So 62690-40-8 is a valid CAS Registry Number.

Estimating pKa values for pentaoxyphosphoranes.
Davies,Doltsinis,Kirby,Roussev,Sprik
, p. 6594 - 6599 (2002)
pKa values are estimated independently, by two entirely different methods, for the ionizations of the apical and equatorial OH groups of two representative hydroxyphosphoranes. A bond length-pKa correlation based on crystal structures of cyclohexanol deri
