Check Digit Verification of cas no

The CAS Registry Mumber 206860-63-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,6,8,6 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 206860-63:
(8*2)+(7*0)+(6*6)+(5*8)+(4*6)+(3*0)+(2*6)+(1*3)=131
131 % 10 = 1
So 206860-63-1 is a valid CAS Registry Number.

New strategy for the diastereoselective synthesis of bicyclic 'pre- activated' analogues of cyclophosphamide

Maynard-Faure,Gonser,Vaime,Bouchu

, p. 2315 - 2318 (1998)

The diastereoselective synthesis of 'pro-activated' analogues of cyclophosphamide in the 3-[bis(2-chloroethyl)amino]-2-aza-4,9-dioxa-3- phosphabicyclo(4.3.0)nonane 3-oxide series is described, using either the phosphorylation of an azidoalcohol followed by a reductive cyclisation or the phosphorylation of an acetal alcohol followed by an unprecedent direct Lewis acid catalyzed intramolecular substitution.
