1260148-64-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1260148-64-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,0,1,4 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1260148-64:
(9*1)+(8*2)+(7*6)+(6*0)+(5*1)+(4*4)+(3*8)+(2*6)+(1*4)=128
128 % 10 = 8
So 1260148-64-8 is a valid CAS Registry Number.

A diastereoselective formal synthesis of berkelic acid
Wenderski, Todd A.,Marsini, Maurice A.,Pettus, Thomas R. R.
, p. 118 - 121 (2011/04/15)
A formal synthesis of berkelic acid is reported. The strategy employs the combination of a chiral exocyclic enol ether and an achiral isochromanone to afford the chroman spiroketal core via a base-triggered generation and cycloaddition of an o-quinone met
