76782-19-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 76782-19-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,7,8 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 76782-19:
(7*7)+(6*6)+(5*7)+(4*8)+(3*2)+(2*1)+(1*9)=169
169 % 10 = 9
So 76782-19-9 is a valid CAS Registry Number.

Preparative synthesis of ethyl 5-acyl-4-pyrone-2-carboxylates and 6-aryl-, 6-alkyl-, and 5-acylcomanic acids on their basis

Obydennov,Goncharov,Sosnovskikh, V. Ya.

, p. 2233 - 2242 (2017/05/12)

A simple and efficient method for the synthesis of ethyl 5-alkanoyl- and 5-aroyl-4-pyrone-2-carboxylates was developed, which is based on the condensation of 1-R-2-(dimethyl-aminomethylidene)butane-1,3-diones, obtained from 1,3-diketones and dimethylforma
