1268465-69-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1268465-69-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,4,6 and 5 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1268465-69:
(9*1)+(8*2)+(7*6)+(6*8)+(5*4)+(4*6)+(3*5)+(2*6)+(1*9)=195
195 % 10 = 5
So 1268465-69-5 is a valid CAS Registry Number.

A short asymmetric route to the bromophycolide A and D skeleton
Lin, Hongkun,Pochapsky, Susan S.,Krauss, Isaac J.
, p. 1222 - 1225 (2011/05/06)
An asymmetric synthesis of the bromophycolide D ring system has been achieved in seven steps from a known geranylgeranylated benzoate, via bromonium-promoted transannular cyclization of a macrocyclic intermediate.(Figure Presented)
