Check Digit Verification of cas no

The CAS Registry Mumber 3839-63-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,3 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3839-63:
(6*3)+(5*8)+(4*3)+(3*9)+(2*6)+(1*3)=112
112 % 10 = 2
So 3839-63-2 is a valid CAS Registry Number.

Base catalyzed sustainable synthesis of phenyl esters from carboxylic acids using diphenyl carbonate

Kreye, Oliver,Meier, Michael A. R.

, p. 53155 - 53160 (2015)

Phenyl esters were obtained in moderate to high yields by reaction of aliphatic and aromatic carboxylic acids with one equivalent of diphenyl carbonate in the presence of catalytic amounts of tertiary amine bases, such as DBU, TBD and DMAP under neat conditions at elevated temperatures (>100°C).

Effect of solvent and ultrasound on esterification of phenols

Rama,Pasha

, p. 2604 - 2605 (2007/10/03)

Phenols are conveniently acylated by acid chlorides in CH2Cl2 under the influence of ultrasound to give esters in satisfactory yields.
