Check Digit Verification of cas no

The CAS Registry Mumber 5203-83-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,0 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5203-83:
(6*5)+(5*2)+(4*0)+(3*3)+(2*8)+(1*3)=68
68 % 10 = 8
So 5203-83-8 is a valid CAS Registry Number.

Phospha-Michael-type reactions between 1,2-diaza-1,3-dienes and bidentate nucleophiles: Formation of new mono- and diylides and their elaboration to heterocycles

Boga, Carla,Zanna, Nicola,Attanasi, Orazio A.,Baccolini, Graziano,De Crescentini, Lucia,Forlani, Luciano,Mantellini, Fabio,Nicolini, Simona,Micheletti, Gabriele,Tozzi, Silvia

experimental part, p. 1326 - 1334 (2011/04/17)

Phospha-Michael additions of a series of methylene-bridged phosphorus bidentate nucleophiles to 1,2-diaza-1,3-dienes gave monoadducts and bisadducts in high yields under mild conditions. In particular, a series of new ylides and symmetrical diylides have been obtained from bis(diphenyl)phosphanes. The use of diphenylphosphanylamino derivatives gave, through phospha-Michael addition, ylide intermediates that underwent spontaneous intramolecular attack by the amino group belonging to the Michael donor reagent moiety, thus giving access to new heterocycles.
