Check Digit Verification of cas no

The CAS Registry Mumber 139935-28-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,9,3 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 139935-28:
(8*1)+(7*3)+(6*9)+(5*9)+(4*3)+(3*5)+(2*2)+(1*8)=167
167 % 10 = 7
So 139935-28-7 is a valid CAS Registry Number.

PHOSPHONIC SYSTEMS. 7. REACTIONS OF 2,3-EPOXYPHOSPHONATES WITH NUCLEOPHILES: PREPARATION OF 2,3-DISUBSTITUTED ALKYLPHOSPHONIC ESTERS AND RELATED SYSTEMS

Phillips, A. M. M. M.,Mphahlele, M. J.,Modro, A. M.,Modro, T. A.,Zwierzak, A.

, p. 165 - 174 (2007/10/02)

Diethyl 2,3-epoxyalkylphosphonates react regioselectively with various nucleophilic reagents yielding 2-hydroxy-3-substituted alkylphosphonic esters.The 2-hydroxy functionality can be easily converted into an ester or ether derivative.The reaction of diethyl 2,3-epoxypropylphosphonate with ketone enamines does not lead to hydroxyketophosphonates, but results in the corporation of the 3-phosphonopropylidene group (CH-CH2-PO3Et2) into the position 2 of the parent ketone.Key words: 2,3-Epoxyphosphonates; nucleophilic opening of epoxides; reaction of epoxides with enamines; 2-(3'-diethoxyphosphonyl)propylidenecycloalkanones.
