77251-53-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77251-53-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,2,5 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77251-53:
(7*7)+(6*7)+(5*2)+(4*5)+(3*1)+(2*5)+(1*3)=137
137 % 10 = 7
So 77251-53-7 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.
