Check Digit Verification of cas no

The CAS Registry Mumber 1014711-45-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,4,7,1 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1014711-45:
(9*1)+(8*0)+(7*1)+(6*4)+(5*7)+(4*1)+(3*1)+(2*4)+(1*5)=95
95 % 10 = 5
So 1014711-45-5 is a valid CAS Registry Number.

Unprecedented intramolecular nucleophilic aromatic additions of allyloxy anions to diphenylphosphinoyl-substituted benzene rings: A facile method for preparing multisubstituted benzopyrans

Gorobets, Evugeni,Parvez, Masood,Keay, Brian A.

, p. 129 - 133 (2008)

A new synthetic method for the preparation of multisubstituted benzopyrans that involves an intramolecular conjugate addition of allyloxy anions to diphenylphosphinoyl-substituted benzene rings is described. The intermediate anion is trapped with electrophiles providing benzopyrans that are readily oxidized with O2 to intermediates containing a peroxide that is easily converted into benzopyran-2-ones (i.e. coumarins).
