40525-15-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40525-15-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,5,2 and 5 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 40525-15:
(7*4)+(6*0)+(5*5)+(4*2)+(3*5)+(2*1)+(1*5)=83
83 % 10 = 3
So 40525-15-3 is a valid CAS Registry Number.

A novel synthetic route for making (-)-CBD and its derivatives bearing various C4′-side chains is developed by a late-stage diversification method. Starting from commercially available phloroglucinol, the key intermediate (-)-CBD-2OPiv-OTf is efficiently and regioselectively prepared and further undergoes Negishi cross-coupling to furnish (-)-CBD. This approach allowed an efficient synthesis of (-)-CBD in a five-step total 52% yield on a 10 g scale. Furthermore, diversification on the C4′-side chain with this method can be realized in a wide range.
