90295-68-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 90295-68-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,2,9 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 90295-68:
(7*9)+(6*0)+(5*2)+(4*9)+(3*5)+(2*6)+(1*8)=144
144 % 10 = 4
So 90295-68-4 is a valid CAS Registry Number.

(Chemical Equation Presented) A short, convergent synthesis of the mushroom pigment norbadione A is described. The construction of an appropriately substituted naphtholactone intermediate involved a regioselective Diels-Alder reaction between a bis(triisopropylsilyloxy)diene and 2,6-dichlorobenzo-1,4- quinone. A double Suzuki-Miyaura cross-coupling between a diboronate and two identical enol triflates was another key feature of the synthesis.
