76200-33-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76200-33-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,2,0 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 76200-33:
(7*7)+(6*6)+(5*2)+(4*0)+(3*0)+(2*3)+(1*3)=104
104 % 10 = 4
So 76200-33-4 is a valid CAS Registry Number.

ON THE REACTION OF ORSELLINIC ACID CARBANION WITH PYRYLIUM SALTS
Hoefle, Gerhard,Schneider, Guenther,Roeser, Karl
, p. 1633 - 1636 (2007/10/02)
From the reaction of methyldimethyl orsellinate anion 1 with the pyrylium salt 2 the isocumarin 5 was isolated in addition to the pyrones 3 and 4.Reaction intermediates could be trapped as pyridines 6 and 7.
