General Description

1-Cyclopentene-1-heptanoic acid, 5-oxo-3-[(triethylsilyl)oxy]-, Methyl ester is a chemical compound that is commonly used as a building block in organic synthesis. It is a methyl ester of a carboxylic acid and contains a cyclopentene ring, a heptanoic acid chain, and a triethylsilyl group. The triethylsilyl group can serve as a protecting group for sensitive functional groups in chemical reactions. 1-Cyclopentene-1-heptanoic acid, 5-oxo-3-[(triethylsilyl)oxy]-, Methyl ester has applications in pharmaceutical and agrochemical industries, where it can be used as an intermediate in the synthesis of various bioactive compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 112713-92-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,7,1 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 112713-92:
(8*1)+(7*1)+(6*2)+(5*7)+(4*1)+(3*3)+(2*9)+(1*2)=95
95 % 10 = 5
So 112713-92-5 is a valid CAS Registry Number.
