Check Digit Verification of cas no

The CAS Registry Mumber 667899-63-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,7,8,9 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 667899-63:
(8*6)+(7*6)+(6*7)+(5*8)+(4*9)+(3*9)+(2*6)+(1*3)=250
250 % 10 = 0
So 667899-63-0 is a valid CAS Registry Number.

Synthesis of 3-(3,5-dioxo-[1,2,4]-oxadiazolidin-2-yl)propylphosphonic acids

Kurz, Thomas,Geffken, Detlef,Wackendorff, Claudia

, p. 39 - 49 (2003)

Cyclic carbonylation of hydroxyureas 3 with 1,1′-carbonyldiimidazole gave 3-(3,5-dioxo-[1,2,4]oxadiazolidin-2yl)propylphosphonic acid diethyl esters 4 which were converted into the corresponding phosphonic acids 5 with bromotrimethylsilane.
