1225384-06-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1225384-06-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,5,3,8 and 4 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1225384-06:
(9*1)+(8*2)+(7*2)+(6*5)+(5*3)+(4*8)+(3*4)+(2*0)+(1*6)=134
134 % 10 = 4
So 1225384-06-4 is a valid CAS Registry Number.

Stereoselective synthesis of enantiopure analogues of (-)-cephalotaxine
Berhal, Farouk,Perard-Viret, Joelle,Royer, Jacques
experimental part, p. 325 - 332 (2010/06/12)
The asymmetric total synthesis of three analogues of (-)-cephalotaxine with structural modification of the aromatic ring was achieved in 16 steps and acceptable overall yields. The procedure used was quite similar to that reported by our group for the tot
