Check Digit Verification of cas no
The CAS Registry Mumber 40656-50-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,6,5 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 40656-50:
(7*4)+(6*0)+(5*6)+(4*5)+(3*6)+(2*5)+(1*0)=106
106 % 10 = 6
So 40656-50-6 is a valid CAS Registry Number.

CONVENIENT OXIDATIONS OF CARBOHYDRATE DERIVED LACTOLS AND OF ε-HYDROXY-β-KETOPHOSPHONATES
Csuk, Rene,Doerr, Petra
, p. 35 - 44 (2007/10/02)
Convenient oxidation of carbohydrate derived lactols to lactones as well as the oxidation of ε-hydroxy-β-ketophosphonates to their corresponding β,ε-diketophosphonates can be performed with the Dess-Martin periodinane in high yields.
