Check Digit Verification of cas no

The CAS Registry Mumber 131613-01-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,6,1 and 3 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 131613-01:
(8*1)+(7*3)+(6*1)+(5*6)+(4*1)+(3*3)+(2*0)+(1*1)=79
79 % 10 = 9
So 131613-01-9 is a valid CAS Registry Number.

SYNTHESIS OF (19e)-17Β-HYDROXY-3-OXOANDROST-4-EN-19-AL-19-(O-CARBOXYMETHYL)OXIME

Fajkos, Jan,Pouzar, Vladimir,Veres, Karel

, p. 2086 - 2094 (2007/10/02)

The title compound XIII was synthesized from epoxide I.Cleavage with zinc dust and Jones' oxidation under mild conditions afforded aldehyde V.Reaction with (O-carboxymethyl)hydroxylamine hemihydrochloride followed by methylation with diazomethane led to oxime X which on partial hydrolysis gave the 3-hydroxy derivative VIII.Its oxidation accompanied with a rearrangement of the double bond yielded ketone XVI which on hydrolysis afforded the desired hapten XIII.
