1136-23-8 Usage
General Description
3-(2-methylphenyl)dihydro-2H-pyran-2,6(3H)-dione, also known as 2-methylphthalide, is a chemical compound with the molecular formula C11H10O3. It is a cyclic compound with a dihydro-2H-pyran-2,6(3H)-dione core and a 2-methylphenyl group attached to it. 2-methylphthalide is used in the synthesis of pharmaceuticals and agrochemicals and has also been studied for its potential therapeutic effects, including its anti-inflammatory and antitumor properties. It is also used as a flavoring agent in the cosmetic and food industries. However, it is important to note that 2-methylphthalide may have potential health and environmental hazards, and thus careful handling and disposal procedures should be followed.
Check Digit Verification of cas no
The CAS Registry Mumber 1136-23-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,3 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1136-23:
(6*1)+(5*1)+(4*3)+(3*6)+(2*2)+(1*3)=48
48 % 10 = 8
So 1136-23-8 is a valid CAS Registry Number.
