Check Digit Verification of cas no

The CAS Registry Mumber 503005-01-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,3,0,0 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 503005-01:
(8*5)+(7*0)+(6*3)+(5*0)+(4*0)+(3*5)+(2*0)+(1*1)=74
74 % 10 = 4
So 503005-01-4 is a valid CAS Registry Number.

Temperature- and time-dependent stereochemical control in thermally induced keto-ene cyclizations

Pedrosa, Rafael,Andres, Celia,Roson, Carlos D.,Vicente, Martina

, p. 1852 - 1858 (2007/10/03)

Reaction conditions determine the stereoselection in the intramolecular keto-ene reaction. The thermolysis of chiral 2-acyl-3-allyl-substituted 1,3-perhydrobenzoxazines derived from (-)-8-aminomenthol gives a mixture of only two cis-3-hydroxy-3,4-disubstituted pyrrolidine nuclei. The stereochemistry of the major diastereoisomer depends on both the temperature and the reaction time.
