7766-83-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7766-83-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,6 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7766-83:
(6*7)+(5*7)+(4*6)+(3*6)+(2*8)+(1*3)=138
138 % 10 = 8
So 7766-83-8 is a valid CAS Registry Number.

Synthesis of γ-nitro aliphatic methyl esters via michael additions promoted by microwave irradiation

Escalante, Jaime,Francisco, D. Diaz-Coutino

experimental part, p. 1595 - 1604 (2010/03/24)

A simple and efficient protocol has been developed for the direct synthesis of γ-nitrobutyric acid methyl esters under microwave irradiation. This methodology reduces reaction times from days to minutes, compared to conventional conditions. Additionally, these conditions increased yields and provided cleaner reactions.
