Check Digit Verification of cas no
The CAS Registry Mumber 561-51-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,6 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 561-51:
(5*5)+(4*6)+(3*1)+(2*5)+(1*1)=63
63 % 10 = 3
So 561-51-3 is a valid CAS Registry Number.

Construction of "normal"- and "iso-type" oxazolidine rings in C20-diterpenoid alkaloids: Oxidative cyclization with potassium ferricyanide

An efficient and simple method using alkaline ferricyanide for converting the NCH2CH2OH group-containing alkaloid derivatives into their "normal"- and "iso-type"-oxazolidine ring-containing alkaloids has been developed. This is the first one-step oxidation method which affords both types of oxazolidine rings simultaneously.
