33442-48-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 33442-48-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,4,4 and 2 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 33442-48:
(7*3)+(6*3)+(5*4)+(4*4)+(3*2)+(2*4)+(1*8)=97
97 % 10 = 7
So 33442-48-7 is a valid CAS Registry Number.

A regiocontrolled synthesis of codonocarpine
Humora, Michael J.,Seitz, David E.,Quick, James
, p. 3971 - 3974 (2007/10/02)
The total synthesis of the Lunaria alkaloid codonocarpine is described. Regiospecific formation of the macrocycle is achieved by the use of a properly protected spermidine unit.
