General Description
(E)-3-Methyl-2-phenyl-8-(prop-1-enyl)-4H-1-benzopyran-4-one, also known as isocoumarin, is a chemical compound with the molecular formula C18H16O2. It is a derivative of coumarin and is commonly found in plants such as the tonka bean. Isocoumarin has been studied for its potential therapeutic properties, including its anticoagulant and antimicrobial effects. It is also used as a building block in organic synthesis for the production of various pharmaceuticals and agrochemicals. Isocoumarin exhibits a yellow color and has a characteristic sweet, vanilla-like scent. However, it should be handled with caution as it is considered to be toxic if ingested or inhaled in large quantities.
Check Digit Verification of cas no
The CAS Registry Mumber 97070-55-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,0,7 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 97070-55:
(7*9)+(6*7)+(5*0)+(4*7)+(3*0)+(2*5)+(1*5)=148
148 % 10 = 8
So 97070-55-8 is a valid CAS Registry Number.

2-Hydroxy-3-(alkoxycarbonyl or prop-1-enyl)phenyl alkyl ketones are easily converted into 2,8-disubstituted (3-methyl)-4H-1-benzopyran-4-ones through a new DBU (1,8-diazabicyclo[5.4.0]undec-7-ene) assisted one-pot synthesis, by reaction with aroyl or alkanoyl chlorides or anhydrides. The method is simple, mild and convenient as compared to the existing multistep procedures.
